No, I just had studio Manager open. I could not find a way to view or use UDk's on Studio Manager (other than to set them up). If you are not using scenes already, or have extra scenes, you could set up individual scenes that just recall channel on / off settings. You could then just recall those scenes from studio Manager as needed.
Please explain. Unless the total number of scenes that you both want to use is greater than 300, you should be able to coexist.
IIRC the IDKs are global - they cannot be saved on a scene by scene basis. However each user can save his own configuration to a USB stick and load it for his show.
