Okay, so things have been going well, but I've run into an unusual problem. I just realized I can't tag 'things'. I seem to remember being able to in standard Doom Builder. Is there something different with GZDoom builder or am I missing something?

The idea is to spawn a Baron at this point in the level. Trying to fight him and everything else in the room makes it a little hectic, so I wanted him to spawn as the player approaches the button for the exit door.
