Temp Scroll to Track command?

You can also combine these two scripts.
If you put this on a stream deck button then pressing it will scroll to the stored track. Pressing it with the option key held will store a new scroll track.

If you want to use a keyboard trigger then assign two triggers and make sure that the second trigger contains the option key:

sf.ui.proTools.appActivate()

function csScrollToTrack(trackName) {
    var confirmationDialogWin = sf.ui.proTools.confirmationDialog;
    var scrollTargetTrack = (typeof trackName == "object") ? trackName[0] : trackName;

    try {
        sf.ui.proTools.menuClick({ menuPath: ['Track', 'Scroll to Track...'] });

        confirmationDialogWin.elementWaitFor({ timeout: 100 });

    } catch (err) {

        sf.ui.proTools.refreshMenuItems()

        sf.ui.proTools.appActivateMainWindow();

        sf.ui.proTools.menuClick({ menuPath: ['Track', 'Scroll to Track...'] });

        const dlg = sf.ui.proTools.confirmationDialog;

        sf.waitFor({
            callback: () => {
                dlg.invalidate();
                return dlg.buttons.whoseTitle.is("OK").first.exists;
            },
            timeout: 1000
        }, `Failed waiting for the scroll track dialog`);

    }

    confirmationDialogWin.textFields.first.elementSetTextFieldWithAreaValue({
        value: scrollTargetTrack,
        useMouseKeyboard: true
    });

    sf.waitFor({
        callback: () => confirmationDialogWin.textFields.first.value.invalidate().value == scrollTargetTrack
    })

    confirmationDialogWin.buttons.whoseTitle.is('OK').first.elementClick();

    confirmationDialogWin.elementWaitFor({ waitType: 'Disappear' });
};

const storeScrollTrack = event.keyboardState.hasAlt;

const newTargetScrollTrack = sf.ui.proTools.selectedTrackNames[0]

const {targetScrollTrack} = globalState;


if (!targetScrollTrack || storeScrollTrack) {
    globalState.targetScrollTrack = newTargetScrollTrack

    sf.interaction.notify({
        title: "New temp scroll track is:",
        message: newTargetScrollTrack
    })

    throw 0
}


csScrollToTrack(targetScrollTrack)

That is perfect Chris.
I owe you a beer!

Here's a version that you can use to store as many scroll-to tracks as you need.
Make a copy the script for each scroll track button you need to create and change the value of const storedScrollTrackNumber. Rename the scripts as necessary, place them on your stream deck and you should be good to go.

const storedScrollTrackNumber = 1; // <<---- change this for each track / button you want to store


sf.ui.proTools.appActivate()

function csScrollToTrack(trackName) {

    var confirmationDialogWin = sf.ui.proTools.confirmationDialog;
    var scrollTargetTrack = (typeof trackName == "object") ? trackName[0] : trackName;

    try {
        sf.ui.proTools.menuClick({ menuPath: ['Track', 'Scroll to Track...'] });

        confirmationDialogWin.elementWaitFor({ timeout: 100 });

    } catch (err) {

        sf.ui.proTools.refreshMenuItems()

        sf.ui.proTools.appActivateMainWindow();

        sf.ui.proTools.menuClick({ menuPath: ['Track', 'Scroll to Track...'] });

        const dlg = sf.ui.proTools.confirmationDialog;

        sf.waitFor({
            callback: () => {
                dlg.invalidate();
                return dlg.buttons.whoseTitle.is("OK").first.exists;
            },
            timeout: 1000
        }, `Failed waiting for the scroll track dialog`);

    }

    confirmationDialogWin.textFields.first.elementSetTextFieldWithAreaValue({
        value: scrollTargetTrack,
        useMouseKeyboard: true
    });

    sf.waitFor({
        callback: () => confirmationDialogWin.textFields.first.value.invalidate().value == scrollTargetTrack
    })

    confirmationDialogWin.buttons.whoseTitle.is('OK').first.elementClick();

    confirmationDialogWin.elementWaitFor({ waitType: 'Disappear' });
};

const storeScrollTrack = event.keyboardState.hasAlt;


if (!globalState.targetScrollTracks) globalState.targetScrollTracks = {};

const { targetScrollTracks } = globalState;


if (!targetScrollTracks[storedScrollTrackNumber] || storeScrollTrack) {
    const newTargetScrollTrack = sf.ui.proTools.selectedTrackNames[0];

    globalState.targetScrollTracks[storedScrollTrackNumber] = newTargetScrollTrack;
    
    sf.interaction.notify({
        title: `New temp scroll track #${storedScrollTrackNumber} is:`,
        message: targetScrollTracks[storedScrollTrackNumber]
    })
    throw 0
}


csScrollToTrack(targetScrollTracks[storedScrollTrackNumber])
