Split RGBW light into separate channels

I have a GLedOpto zigbee RGBW controller, but I’m using it to control separate monochrome strips with each channel.

Is it possible to tell home assistant to treat this as 4 separate lights, rather than a combined light that can change colour?

Can you even set them independently with the mixed value? If I set it to red and adjust the temperature it turns green and blue back on too, and setting rgb turns w off.

For what it’s worth, I dictched the GLedOpto device and replaced it with a Shelly RGBW device, which does provide exactly this feature!
