Hmm. Ok, thanks guys. Setting the GC value by hand before applying the VSS Prop is what I've been doing, but was looking for an automated way. Maybe Bagginsbill knows off the top of his head if the file property table is preserved across invocationns of Poser Pro; Then I'd only have to set it up once in the lifetime of the file. If he doesn't know, I suppose I could force myself to check.

Whichway

P.S. - I checked and the table is not preserved across invocations. Not surprising, I suppose, but it means I have to fiddle the GC value once each time I use the file in any Poser Pro session. sigh
