sortable('cancel') on a master sortable


I have 3 sortables ('#master', '#child1', '#child2'). I'd like to
reset the #master list after every drag/drop event (either internally
or externally). In other words, the master list will always be the
same. Ideas on how to accomplish this?
I originally tried using 2 droppables, and 1 draggable using a clone
helper. This did not work for some unknown reason and sortable was
the closest I could get to having a workable solution.
