How to batch round courners of PolyRegions and/or Fill's

[DutchGert]

I have a board with a lot of switching power supplies. Since I use a lot of fills the I decided to use Solid Region's instead of 'real' Polygon Pours to place large area's of copper.

Now I see that all these fills have rectangular corners. Ofcourse I can select a fill and manualy place an Arc on its corners but is it also possible to add a (predefined) Arc on all selected objects?
