Ademco Vista 20P AD2USB Notify which sensor tripped alarm

I know this has been discussed here before, but I have never seen a solution. I have all the virtual relays(or whatever it’s called) setup. My cheatsheet has the serial #'s and loops. However, I’ve never figured out how to get a notification of what sensor tripped the alarm(preferably in countdown mode before alarm sounds). I know I could make 30+ scenes that notify me and are triggered each by a single sensor/zone, but I’ve got to believe there’s are better way. Has anyone had success with this?
