Incrementing a Duplicated Track Name

Hey all,

I'm loving what I'm starting to be able to do with Soundflow - and although I'm a total Java newbie and I'm very much bodging my way through it with bits of other scripts and macro's, I'm starting to get some great results.

I've built a script that uses a little of @Andrew_Scheps 'Increment New Playlist' script and modifies it to apply to a duplicated track. It's working ok, although may be a little clunky. What I'm struggling with is how to get it to add a number if one doesn't exist already.

So for example: "Fuzz Gtr 1" will be duplicated and the new name will be "Fuzz Gtr 2". However, if the original track was called "Fuzz Gtr" the script can't update the number. How could I have it check if a number exists, and if not, add it? Any help gratefully received!

Cheers,
Tim

sf.ui.proTools.trackDuplicateSelected({
    duplicateActivePlaylist: false,
    duplicateAlternatePlaylists: false,

//Remove .dup1 from existing name
var oldTrackName = sf.ui.proTools.selectedTrackNames[0];
var oldTrackName = oldTrackName.split('.').slice(0, -1).join('.');

//Get and Increment Last Number
function getAndIncrementLastNumber(str) {
    return str.replace(/\d+$/, function (s) {
        return ++s;
    });
}

//Variable for new track name
var newTrackName = getAndIncrementLastNumber(oldTrackName);


sf.ui.proTools.selectedTrack.trackOpenRenameDialog({
    renameAllSelectedTracks: false,
});


//Wait for Rename Track window to appear
sf.ui.proTools.windows.first.elementWaitFor({ waitType: "Appear", });



sf.ui.proTools.windows.first.textFields.whoseTitle.is('').first.elementSetTextFieldWithAreaValue
    ({ value: newTrackName });

//Click OK in Rename Track window
sf.ui.proTools.windows.first.buttons.whoseTitle.is('OK').first.elementClick();
