Using a Mask to isolate areas for the Stabilizer?

Is it possible to use a Mask or a Window to Isolate areas that the Stabilizer uses or doesn't use?
I'm finding that in any shot where there is a face, I can't use the stabilizer because the tracker is using the face as it's tracker feature and stabilizing the shot around the face. Which looks weird and is never what I want.
I would be able to get a much better stabilize if I could block the Stabilizer from seeing the face.
