Yes you can. Close the cage, then in tool options switch to "Create or
edit mode". Then you can adjust the cage untill you switch back to
transform mode.

Cage transform is only defined for the interior of the cage. It's a
limitation of the algorithm. The fill works based on the pixel under
your first point. It's ideal operating environment is an element on a
separate layer of a larger canvas with transparent bg. Cage is
somewhat special transform. It strives to be shape preserving.
