The IntersectAction per se doesn't support that.
But given that Actions keep a local copy of their callbacks, you can
create an IntersectAction and just overwrite the Geometry callback with
one that intersects the bbox. Take a look at testIntersectAction.cpp for
some hints how to do that, you just need to use
IntersectAction::registerEnterFunction on your Action instance to
replace the callback just for this action.
Hope it helps
