If that's the correct expansion, just say no. It should be a give away when you find you need "coarse versioning" for your version control system that what you have is a liability. Rather than thrash around trying to find ways to keep VSS sort-of working it should be a priority to migrate away from it.
This isn't some partisan thing, I don't care if you migrate to git or Perforce or even Team Foundation Server. But get off Visual SourceSafe. Once you're safely running a real version control system you'll find that your headache goes away without any need for "coarse versioning" using snapshots.
