"Combine" Saved Games (VSAV)

Is there a way for me to “combine” two saved game vsav files?

I would like to have the piece positions and states from two different vsav files (from same module & map configuration) combined, and not have to manually (and laboriously - big vsav files) add one to the other.

If not, perhaps someone knows a way around this to extract the needed info from the vsav files?
