Tool Palettes & Tool Palette Group Names

I have created multiple tool palettes that i load depending on whether im working on a rcp plan or a toilet room plan, etc. On the right hand side it says Tool Palettes - All Palettes. Does anyone know how to rename that to say rcp,civil, etc? If I right click on the right side of the tool palette & select rename it renames all tool palettes to whatever I type in. I thought it might be tool palette groups but I am not sure. I can't seem to set one to be current. The selection is grayed out
