Insert plugin on first free insert of all selected tracks

The following script will insert the EQ plugin on the first free slot of all the selected tracks. The difference here in making it faster is that it will first find out all the first free slots on all the selected tracks, and then select the tracks according to the grouped free slots and insert it in one go. This way it doesnt have to insert on each track one at a time and is much faster.

sf.ui.proTools.appActivateMainWindow();

var pluginPath = ["multi-mono plug-in", "EQ", "EQ3 7-Band (mono)"];

// Function to find the first free insert slot of a track
function findFirstFreeInsert(track) {
    return track.insertButtons.findIndex(btn => btn.invalidate().value.value === 'unassigned') + 1;
}

// Function to select a track by name
function selectTrackByName(trackName) {
    sf.ui.proTools.trackGetByName({ name: trackName }).track.trackScrollToView();
    sf.ui.proTools.trackSelectByName({ names: [trackName] });
}

// Function to insert a plugin into the selected tracks
function insertPlugin(insertNumber) {
    sf.ui.proTools.selectedTrack.trackInsertOrSendSelect({
        pluginNumber: insertNumber,
        pluginPath: pluginPath,
        selectForAllSelectedTracks: true,
    });
}

// Get the names of all selected tracks and group them by their first free insert slot
const selectedTrackNames = sf.ui.proTools.selectedTrackNames;
const tracksGroupedByInsert = selectedTrackNames.reduce((acc, trackName) => {
    selectTrackByName(trackName);
    const freeInsertIndex = findFirstFreeInsert(sf.ui.proTools.selectedTrack);
    if (freeInsertIndex > 0) {
        acc[freeInsertIndex] = acc[freeInsertIndex] || [];
        acc[freeInsertIndex].push(trackName);
    }
    return acc;
}, {});

// Iterate over each group and insert the plugin
Object.entries(tracksGroupedByInsert).forEach(([insertNumber, trackNamesInGroup]) => {
    sf.ui.proTools.trackSelectByName({ names: trackNamesInGroup });
    insertPlugin(parseInt(insertNumber));
});
