Adding new Midi Controller Assignments to just one subsession

[tullsterx]

I have like 100 subsessions in my Live Performance session.

Every time I add a new Midi Assignment it's automatically turned on in ALL 100 subsessions. Is there anyway for me to stop this? I want to add a new MIDI controller assignment and have it just be active in the new subsession I'm working on without having to go into every existing subsession and turn it off.

Any ideas? Is there a setting somewhere for this?

Anyone?
