Fibaro RGBW Controller with 4 White LED strips

Hi,

I have a Fibaro RGBW controller with 4 separate LED White LED strips connected (rather than one RGBW Led Strip) I can play around with the colour settings inside the SmartThings app to control each of the strips but it would be easier if I could control the brightness of each of the channels individually. IS there any way I can do this?
