Looking at the source, I'd say no.  There's no "plow" code for polygons,
so a poly would never be removed from another poly.  If you draw a line
in the shape of a box around the area, it will clear out the area.  Beware
that when you orphan areas of a polygon like that, the largest remaining
area is the one that survives.  You can get odd effects when a large
portion of your polygon is hidden (eg you add a component to the surviving
side and it shrinks enough that another island becomes dominant).
