Syncing RGBW Controllers

I have multiple Fibaro RGBW controllers in my home (3) all are currently controlling different parts of my under counter and above counter accent lighting I am currently running Fibaro RGBW 3 Beta by Todd Wackford. I would like the ability to sync them, lets say for example I want to do a Fade between all colors, I want all 3 of my controllers to be on the same color at the same time. How would I make that happen? Same as if/when I add accent lights to my livingroom, i would want those to be synced together.

Thank you both for your suggestions!
