Velocity Layering Colors

When I’m layering multiple samples on one key in the keyzones panel for added snare fatness or extra hihat nuance I always think it would be quite useful to be able to resize the keyzones panel vertically and to be able to assign separate colors to each of the samples assigned to the key…perhaps being able to choose a color for each of the samples in the instrument’s sample list from a pallette, or to have colors assigned to them automatically.
