I don't know weather report it as a bug or feature request... So I'll go with a question; Why the hell was this feature removed? There's no single reason I could think of that would justify limiting Zeus's functionality even more, other than it being temporary because of huge technical problems.

Which I doubt are the reason for this. You should strive to expand what Zeus can do as much as you possibly can, not the other way around. The fact I can't spawn FIA terrorists hostile to BLUFOR on the fly or temporarily change players side to make them go undercover or as prisoners, is rather mindbogingly annoying.
