I had read in the manual (can you believe it, ... someone actually does read them.
) that you can have several palette sets, you just have to have them each in their own folder. You cannot have two palette sets in the same folder. With that, you just have to save each palette set to a profile. When you need a particular palette set with the palette tools you need to use, load the profile. Unfortunately, you cannot have two or more tool palette sets on the screen.
However, I have not tested this myself as I am not in need of more than one.
