What is best way of controlling poligon fill ?

Especially for :

1. preventing the fill in unwanted thin tubs and crevasses

Only way I found so far is to draw track with clearance at the inner 
edge of needed area and then filling the clearance between that track 
and contained poly with another track. Cumbersome and results are often 
not exactly as wanted.

2. Filling otherwise unreachable areas within the polygon

When I do for example polygon fill on top (GND) and bottom, I can 
connect otherwise isolated areas with via to the fill on opposing side.
But thing doesn't fill areas it can not reach within the polygon plane, 
so that areas are left empty.

Another polygon doesn't help, since polugon within polygon seems to be 
ignored. Only solutions seems to be a hole and then another polygon 
within it.
