After posting I went on to try PMC (Pulovers Macro Creator) but that proved troublesome, so currently heading the AutoHotKey v2 route. I thank you for providing some code (which I don't understand full) but upon trying I got this error ( I don't expect you to fix it as I do want to try my idea with AHK):
