Insert menu search times with new popup menu handling

The new popup menu handling is awesome for sends and outputs, but I'm seeing some performance issues with inserts. I'm assuming this is because each time the command is run it needs to build a cache of all of the inserts so you can search them. I have thousands of plugins and this is causing it to take a few seconds for the script to continue every time it's run. I wonder if there could be a persistent cache of the plugin menus...

To illustrate, I have a script to insert a plugin on the first available slot (It doesn't go in strict order but that's just me making things complicated). The old version using explicit paths runs very quickly, adding the insert within 2 seconds. The new method with implicit paths (I still have to search separately for mono and stereo since there are no wildcards) takes more than double the time.

Script 1 (Explicit paths):

sf.ui.proTools.appActivateMainWindow();

function getFirstFreeInsertIndex() {
    var btns = sf.ui.proTools.selectedTrack.invalidate().insertButtons;
    let insertArray = [2, 3, 4, 5, 6, 7, 8, 9, 1, 0];
    for (let i = 0; i < insertArray.length; i++)

        if (btns[insertArray[i]].value.invalidate().value === "unassigned") return (insertArray[i]);

    throw 0;
}


sf.ui.proTools.selectedTrack.trackInsertOrSendSelect({
    insertOrSend: "Insert",
    pluginNumber: getFirstFreeInsertIndex() + 1,
    pluginPath: ["plug-in", "EQ", "Scheps Omni Channel (mono)"],
}, function (notMonoTrack) {
    sf.ui.proTools.selectedTrack.trackInsertOrSendSelect({
        insertOrSend: "Insert",
        pluginNumber: getFirstFreeInsertIndex() + 1,
        pluginPath: ["multichannel plug-in", "EQ", "Scheps Omni Channel (stereo)"],
    })
});

Script 2 (new method, slower)

sf.ui.proTools.appActivateMainWindow();

sf.ui.proTools.appActivateMainWindow();

function getFirstFreeInsertIndex() {
    var btns = sf.ui.proTools.selectedTrack.invalidate().insertButtons;
    let insertArray = [2, 3, 4, 5, 6, 7, 8, 9, 1, 0];
    for (let i = 0; i < insertArray.length; i++)

        if (btns[insertArray[i]].value.invalidate().value === "unassigned") return (insertArray[i]);

    throw 0;
}

sf.ui.proTools.selectedTrack.trackInsertOrSendSelect({
    insertOrSend: "Insert",
    pluginNumber: getFirstFreeInsertIndex() + 1,
    pluginSelector: items => items.filter(item => item.path[0] === "plug-in" && item.path.slice(-1)[0] === "Scheps Omni Channel (mono)")[0], 
}, function (notMonoTrack) {
    sf.ui.proTools.selectedTrack.trackInsertOrSendSelect({
        insertOrSend: "Insert",
        pluginNumber: getFirstFreeInsertIndex() + 1,
        pluginSelector: items => items.filter(item => item.path[0] === "multichannel plug-in" && item.path.slice(-1)[0] === "Scheps Omni Channel (stereo)")[0],
    
    })
});
