Rgbw dimmer with 4 white led strips

I bought two type of rgbw dimmer: qubino flush rgbw dimmer and Fibaro. They work correctly with RGB leds but I want to use it with four white led strip. I would like to use them as separated led strip like switch on/off and set brightness one by one. According to datasheets those dimmers are handle this functions but I can’t setup it in smartthings app or ide.

I searched it but noone want this function :slight_smile: , or I can’t find the solution.

How can setup separated strip in smartthings?
