Are there any plans to support them. The way i would expect it to work would be.
Main fixture (Fader 1)
'Global' parameters (pan/tilt, strobe, etc.)
Subfixture 1 (Fader 2)
'Local' parameters (R/G/B, Intensity, etc.)
Subfixture 2 (Fader 3)
'Local' parameters (R/G/B, Intensity, etc.)
Etc.
'Global' parameters would show up in the relevant section for all faders in the fixture. 'Local' parameters would only show under their relevant faders. Virtual intensity would be 'local' with a 'global' virtual intensity for all subfixtures.
