How to create holes in frame with configuration table?

Hi

I want to create frame with holes and be able to use smart fasteners feature in it. The issue is I want this frame in various configuration. Different nubers of holes or distances between holes, differnet sizes of frame and still be able to use smart fastener. I tried various approaches and never fully satisfied .

Please help. Or maybe somebody know how to put skip instances into configuration table so I could change skipped feature. It probably would solve my problem.

Thanks in advance
