The best way I found to get multiple un-numbered hot cues is to use push down to setup grid marker and then invert (release) to make it a cue. Transport wise you switch between them with last/next cue and delete cue deletes the last one.

Yeah you can, as dj gullum says above.
Set a grid marker, name it, press enter so it's stored then change the cue type to whatever you want. You now have a cue point with no number. If you have hotkeys or midi assignments to forward <> backward through cue points you are sorted.
