Does anyone know of a way to reverse the DMM .xml cache files to play the simulation in reverse, similar to nCache's reverse attribute? (Example, shattering a logo, then reversing it to make the logo look like it's reconstructing from the debris?)

Also I know there's been a few posts about bullet time and time remapping the simulation, but any efficient tricks for this technique as well? (Subframe caching, editing keyframes in the graph / trax editor, etc etc)

Any insight would be appreciated, or if this cannot currently be done I would like to request these features!
