What I usually do, as suggested a while back by Kai-Martin, is to
route the entire board with regular tracks (no polygon floods)
including ground and everything.  Only once the layout is
electrically complete (all nets routed) do you lay down the polygon
flood.  This way, the polygon is "optional" and "disposable".
Getting good polygon flooding is really clumsy in pcb right now,
and I usually have to insert multiple smaller polygons in order to
get it to fill everything in, since pcb's "unconnected copper"
filter chops each polygon into a single connected polygon of its
own choosing.

Regards,
Colin
