Changing background color of a Game Piece Palette

Is there such thing as a way to change the background color of a “Game Piece Palette?”

I would like to have something like a grey rather than white so some of my counters that have white in them show up better.

I haven’t found any options when right-clicking on Palette options or components.

Thanks for help or confirmations if this isn’t possible.

No, there’s no option for that presently.

Thank you very much for letting me know!
