Fixtures with more than one RGB-control?

I have some fixtures that have more than one group of LEDs that you can dim and color-control. When creating a custom fixture in Photon 2, I can indeed add multiple color controls, but the UI, only one will be shown. Is this a bug? Or will the single color control send color information to all color channels I have configured in my custom fixture?

I had this same issue. In the end we mapped a bunch of smaller “devices” that controlled the RGBA for a single light in a fixture. It explodes the Light Control area, but does give us control to do individual chases/sequences and control RGBA, dimming, etc for single lights
