Reply to Hotcue mapping

Im currently working on a mapping for my korg nanokontrol to use alongside traktor scratch for looping/effects and cue points. my problem is this; i want to be able to set and delete cue points on the fly by pressing a button to set the hotcue and trigger it, but to delete it hold a shift button and press the corresponding hot cue button (like in the dicer mapping). Im sure im probably overlooking something but i cant find anything about deleting the specific hotcues, can anyone help?

thanks.

edit: just to clarify, im up to the point where i can set the hotcues and iv got a shift button in place, i just need to know how to set it so i can delete them.
