Presently, no. VASSAL 4 might have this capability, insofar is it's
possible to do it sensibly. (There are certain sorts of moves where
it's not clear what the result of undoing them should be. For example,
suppose you move a piece from A to B, then from B to C. The result of
undoing the undoing the first move only seems ill-defined.)
