Exactly, however, extend it a little bit... make it such that it is a little bit more visual... like a medium/small sized window or dialouge that opens up with the catagories listed, by catagory in some type of overlapping style ( like hidden menus ) that have check mark boxes beside them.

Such a window... would be ultimately available in the same way that the right click action would be... or even better, through means of a shortcut key...
