MultiBall and MIDI CC assigning of non consecutive #s

Hey, my question has to do withe the MultiBall and needing to know how to set MIDI CC numbers for the balls that are not consecutive. How do i do that? It only lets me assign a range of CC#'s that are consecutive (i.e. CC #5 through 7 if i have three balls, but what if i want to make it lets say #5, 7, and 9 see how those arent consecutive?)
