Can 2 items be added to the Mask Function.
SFB Fill
Hatch
I know I can pick those by using polyline, but sometimes I need to pick one of the items when they share common edges and vertices.
If you pick associative hatch on the pattern, this works with the polyline mask. In fact, you can always select associative hatch by picking the pattern itself.
This doesn't work for SPB fills, though. My suggestion is to have these on separate layers -- or to also mask for color and entity at the same time. You can combine the mask criteria to really narrow the selection by doing this!
