Can someone help modify @Andrew_Scheps script to accommodate Multiple Output Assignments?

Ok, here you go! This has also been refactored a bit so it isn't just one huge blob of code.

Please note that the folder will always be assigned to the outputs of the top-most selected track when you run the script.

function makeNewFolder(folderTitle) {
    // Open Move to New Folder dialog and set parameters
    sf.ui.proTools.menuClick({
        menuPath: ["Track", "Move to New Folder..."],
    });

    sf.ui.proTools.windows.whoseTitle.is('Move To New Folder').first.elementWaitFor({
        waitType: "Appear",
        timeout: 2500,
    });
    let folderDlg = sf.ui.proTools.windows.whoseTitle.is('Move To New Folder').first;
    let popupButtons = folderDlg.popupButtons;

    //Assign the buttons coming out of the previous instruction to individual variables
    var folderType = popupButtons[0];

    if (folderType.value.invalidate().value != 'Routing Folder')
        folderType.popupMenuSelect({ menuPath: ['Routing Folder'] });

    //Now that it's definitely a routing folder we have the other two popup menus available to assign to variables

    var folderWidth = sf.ui.proTools.windows.whoseTitle.is('Move To New Folder').first.popupButtons.allItems[2];
    var timeBase = sf.ui.proTools.windows.whoseTitle.is('Move To New Folder').first.popupButtons.allItems[1];

    // Set them accordingly

    if (folderWidth.value.value != 'Stereo')
        folderWidth.popupMenuSelect({ menuPath: ['Stereo'] });

    if (timeBase.value.value != 'Samples')
        timeBase.popupMenuSelect({ menuPath: ['Samples'] });

    sf.ui.proTools.windows.whoseTitle.is('Move to New Folder').first.checkBoxes.whoseTitle.is('Route Tracks to New Folder').first.checkboxSet({
        targetValue: "Enable",
    });

    sf.ui.proTools.windows.whoseTitle.is('Move To New Folder').first.textFields.whoseTitle.is('Track name').first.elementSetTextFieldWithAreaValue({
        value: folderTitle,
    });

    // Make it so
    sf.ui.proTools.windows.whoseTitle.is('Move To New Folder').first.buttons.whoseTitle.is('Create').first.elementClick();
    //If there were multiple outputs assigned to any rtrack in the selection we will get a further diaslog
    if (sf.ui.proTools.confirmationDialog && sf.ui.proTools.confirmationDialog.buttons.whoseTitle.is("Replace").exists) {
        sf.ui.proTools.confirmationDialog.buttons.whoseTitle.is("Replace").first.elementClick();
        sf.ui.proTools.confirmationDialog.elementWaitFor({ waitType: "Disappear" })
    }
    sf.ui.proTools.windows.whoseTitle.is('Move To New Folder').first.elementWaitFor({
        waitType: "Disappear",
        timeout: 2000,
    });


}

function reAssignFolderOutputs(originalOutputs, folderTitle) {

    // Refresh PTs track list
    sf.ui.proTools.mainWindow.invalidate();
    //Reselect the new folder
    sf.ui.proTools.trackSelectByName({ deselectOthers: true, names: [folderTitle] });


    //Assign the folder output to the outputs of the first originally selected track

    for (let i = 0; i < originalOutputs.length; i++) {
        sf.ui.proTools.selectedTrack.outputPathButton.popupMenuSelect({
            menuPath: originalOutputs[i],
            isControl: i > 0,

        })
    }
}

function getOutputAssignments() {
    // Set up variables to hold original assignments. NOTE this will only check the top-most selected track
    //Variable to store the current output assignment
    let originalOutputs = sf.ui.proTools.selectedTrack.outputPathButton.popupMenuFetchAllItems().menuItems.filter(mi => mi.element.isMenuChecked).map(ci => ci.names);
    sf.ui.proTools.appActivateMainWindow();
    return originalOutputs
}

function main() {

    // Get Name for New Folder - Keep in mind this will also be the name of the busses used to route the tracks
    var folderTitle = sf.interaction.popupText({ title: 'Name of New Folder' }).text;


    sf.ui.proTools.appActivateMainWindow();
    // Refresh PTs track list
    sf.ui.proTools.mainWindow.invalidate();

    let originalOutputs = getOutputAssignments();

    makeNewFolder(folderTitle);

    reAssignFolderOutputs(originalOutputs, folderTitle);


}

main();

I'm using the HELLLLLL out of this script, Andrew. Thank you :-)
Could anyone help me with making the new folder track color match the color of the original tracks?

function makeNewFolder(folderTitle) {
    // Open Move to New Folder dialog and set parameters
    sf.ui.proTools.menuClick({
        menuPath: ["Track", "Move to New Folder..."],
    });

    sf.ui.proTools.windows.whoseTitle.is('Move To New Folder').first.elementWaitFor({
        waitType: "Appear",
        timeout: 2500,
    });
    let folderDlg = sf.ui.proTools.windows.whoseTitle.is('Move To New Folder').first;
    let popupButtons = folderDlg.popupButtons;

    //Assign the buttons coming out of the previous instruction to individual variables
    var folderType = popupButtons[0];

    if (folderType.value.invalidate().value != 'Routing Folder')
        folderType.popupMenuSelect({ menuPath: ['Routing Folder'] });

    //Now that it's definitely a routing folder we have the other two popup menus available to assign to variables

    // Set them accordingly

    if (folderWidth.value.value != 'Stereo')
        folderWidth.popupMenuSelect({ menuPath: ['Stereo'] });

    if (timeBase.value.value != 'Ticks')
        timeBase.popupMenuSelect({ menuPath: ['Ticks'] });

        value: folderTitle,
