I hope it helps you

EDIT :

I may have misunderstood your question. If what you want is to know which has been the last slot modified from a form, what you can do is to create a new Slot that will be dedicated to store the name of the modified slot.

To do this, every time you call a form, you must then call a Custom Action, different for each form, which will set the value of that Slot with SlotSet. And when you need it you can get the value of that Slot with tracker.get_slot.
