Multichannel led strips controller

Hello HE community,
I couldn't find any topic that would answer my question. Many of RGB CW led controller supports single color mode. But in this mode all 5 channels act as a single channel. Is there any device or a driver that supports really multiple single color strips?
What I want is to be able to set different dim levels at different channels.
I apologize if there is a similar topic

Physically all these RGB(WW/CT) controllers are nothing more than 3 to 5 PWM Individual Dimmers. How Driver treats it is a different story. I am not using any of these but Driver should have at least a separate control for R,G and B channels. You can use them as a individual controllers for single color strips. I.e. R is controlled Strip-1, G is controlled Strip-2 and B is controlled Strip-3. CT/WW channels is a bit different story (unfortunately the existing Drivers are too smart when dealing with CT/WW).

Yeah, however it would be much more convenient to have a device with child devices representing separate channels. So they have clear '0-100 level' property instead of colors that might be confusing.

Just wondering if there is out-of-the box solution or I need to develop custom driver or a mapping script to translate 5-white into RGB+CW

Of course this is personal preferences.
Personally, I don't like all these child devices. If any Child Devices is used more than once I am dechildesign (just made this word) it. The reason is - there is no easy way to replace child devices.
