What happens if you run autovoid on the negative plane, just as you would have done on a positive static (or pre-auto-generated) shape? You would have to re-do it every time you moved a via (or at least once when you think you're done) but I'm guessing it might do what you want...

The via-to-shape and pin-to-shape spacing rules are not being followed. According to Cadence, the via antipad has priority. Can I force the shape to follow the NET_SPACING_TYPE rule? (I don't want a positive shape; I think it would kill my design since it has 22000 vias.)
