Manual "auto bed levelling"

Is there a set of M codes I can enter which mimics the auto bed levelling but with me manually moving the nozzle about and setting the Z height?

So I'd enter "MstartAutoBedLevel", then jog to my left bottom corner, set the extruder to be at the right height. Next enter MtopRightAutoBedLevel, move the carriage to the top right, move the extruder to the right Z point, etc, etc.

Actually it would probably be move to point, then enter M code, but you get the idea

Check out the G30 g-code.

Huzzah!
