Just try to use an actor that has properly states in it that will spawn 2/3 copies of the same actor with A_Jump / A_SpawnItem tricks via decorate (jump for the state, spawn for the desired actor) 2. It's a bit tricky to explain I think, but surely you must use external compiled acs + CallACS functions to get rid such stuff. Sorry to not give to you any clue, I'm a bit busy ATM and I just wanted to be of some help for the purpose.
