Not even beta actually. And no, nobody has it.

As for your question, I don't know, but you might want to ask this in some old Unreal forum, since Jazz 3 runs on Unreal. I've been using Unreal Editor 3 for about nine weeks now, and I know it has a console to execute these kind of commands, which is just pressing Enter. But I don't think it works that way in Jazz 3.
