It can, assuming the plane is "simple" enough.  If there's multiple
planes are on one layer (like my board), or if there are a lot of
signals on the layer, a single rectangle is insufficient.

Note that the most recent pcb knows how to slice up a polygon
(i.e. rectangle) to remove isolated islands.  It should make pours
easier.

I did that for the m3a board.

Glad I could help ;-)

Just keep in mind there are a few "fixes" needed if you want it to
actually work.
