I've never seen any utility to do that, although it sure would have saved me a lot of time as well. 

If you can't automate the process, this might help (in case you don't know): when I switched to not using pmds, and deleted them all from my runtimes, I naturally lost all my morphs I had created with my Daz figures. But I discovered that if you re-inject a figure with the full morphs, the figure will reassume it's morphed shape.  I did this repeatedly with V3 and P6. Still very time consuming, but it did allow me to rid myself forever of the scourge of pmds and still retain my figures and scenes as originally shaped.
