Hi, Randy,

The short answer is:  sorry, there's no way to do this.

The situation here is much like footprints in the sand on the beach: 
if Bob's footprints get crossed and thus obliterated by Wendy's later 
footsteps, there's no way that one can recover Bob's earlier 
footprints.

And if even if one had a way of remembering exactly where Bob's 
footprints had been, it would not do to "erase" them, because that 
would compromise the appearance of the footprints later put down by 
Wendy.

Sorry,

  -- Scott
