OK, I see what you want me to do now. Basically, abandon the 4Bar profile and create 5 pseudo fixtures:
Fixture 1 - 4Bar Control (3-channel)
Fixture 2 - 4Bar RGB Can (3-Channel)
Fixture 3 - 4Bar RGB Can (3-Channel)
Fixture 4 - 4Bar RGB Can (3-Channel)
Fixture 5 - 4Bar RGB Can (3-Channel)
Seems hacky, but I guess it will work.
