'Manipulator Tools >> Cycle Through Position/Orientation': reverse order?

Hi there!
Would it be possible to add to the cycling through the manipulator positions and orientations the opposite order? While at the same time having both in the same action? I mean, just like the 'Polygons By/In Selected Vertices' & it's counterpart 'Polygons In/By Selected Vertices', where in each tool, you have the #-sign to execute the opposite. I want to put the cycling into a radial menu and be able to cycle backwards, when choosing the # of that command.

Done.
