I can't use the "pour over same net" option. I have several dedicated GND returns ...
btw, this is with P99SE SP6.
Actually, you can.
I did exactly the same thing, albeit on a multilayer board.
Here's how:
1) change (only) the dedicated ground return vias to pads
2) create a pad class 'GNDreturn' or something similar and assign the dedicated pads to it
3) create a rule to state that pads belonging to the GNDreturn class do not connect to polys
4)tell the polys to pour over the same net
You may have to repeat steps 2 and 3 to include specific track segments, on my multilayer board those tracks were on inside layers.
Another way to prevent sections from connecting is to outline them with a keepout track on the same layer, applying specific rules to prevent clearances from doubling.
And, as Dennis said: split the dedicated returns into seperate nets and use the famous LVS (Lomax virtual short ;). Works like a charm.....
