Here is my initial expression for the calculated dimension:
Yes, that's possible. You can concatenate the fields to autonumber the combination of the fields or for the combination that should determine the counter. For example autonumber(EventID&EventCategory, Year) or autonumber(EventtID, Year&EventCategory).
