@jb1486 Nope! It would require some rewiring of the actual LED's and adding an LED controller to make this work. The DR controller does not have the required functionality unfortunately.
In the end I bought the ipac ultimate controller and a load of RGB buttons to upgrade my CP.

@MeduZaPaT Will I be able to use the PPA that is listed on the wiki deployment page? It seems like it is from 2020 so I'm concerned it is out of date.

I am using the pi4 with retropie. When I install, do I just need to go about it manually (build)? Was using the PPA even an option for me?

I apologize for such basic questions. Linux has a lot of unknowns to me.
