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.

Yes, you can use "Interactive" mode to see the tracking markers that the Stabilizer is using. Using the controls provided, draw a box around the markers you want the Stabilizer to ignore, and delete them (with the Trashcan icon). You can also insert new markers in other parts of the screen using the controls provided.

As soon as I delete the trackers I don't want, if I hit play, or step forward or backward a frame, all of the features just come right back.
