Yes. Use this method to schedule events in an external scheduler.
1) Create a manual event to do something.
2) Create a short audio file of silence (I made mine 0.1 seconds long) for each event you want to schedule.
3) In Tracks Manager, edit the silent file(s), go to the (I think it's called) Other Tab (the last one on the right) and on end event select your manual event.
4) Add these silent "Trigger" files (Save them as type "Other" in the database as well to your scheduler database.
There you go.
