Color Palettes - Manually Override Color Swatch

I'd love the ability to override the color swatch that displays in direct selects for color palettes. Either choosing a leader channel, or the ability to choose your own RGB value. I have some palettes that choose color wheel chips on movers and those only show white for example. Additionally, if you have RGB fixtures that display less than perfect colors but I have color palettes set to match them as best as possible, it would be nice to be able to see on screen what you're supposed to see.

I know you can combat this by putting a fixture at the very highest channel stored in the color palette to  combat this, but having that functionality built in would be awesome..
