Multiple MIDI Tx Source ID configurations

It's becoming common to need to send MIDI triggers to multiple departments, each with their own cue list and needs.  It would be nice to be able to configure multiple MIDI Tx Source IDs with their own MIDI settings (notably MIDI Cue List), so that gateways set to ID 1 send MIDI triggers from Cue List 1, ID 2 sends MIDI triggers from Cue List 4, etc.

This would be handy to keep the MIDI lines from being noisy, and (more importantly) be able to, during tech, get specific about which department I'm sending MIDI triggers to, so that I can be sure that video will follow me, but I won't be accidentally setting off sound effects.
