Reply to MF Spectra Button-Color Mod

Hi. Is it possible to order or mod the color of the buttons on a MF Spectra? For example, I want 2 red and 2 blue buttons in the first row, 1 green and 3 yellow buttons in the second row, all purple buttons in the third row, etc.

It seems like I can only order a Spectra with different colored buttons per row. (i.e. each row has to be the same color). Is that true?

Apologies if this has been answered on the community before. Please point me to the thread.

Thanks!
