Smart Mate With Custom Hardware

A bit confused here.

I have a custom standoff that need to go in holes that have unique locations with an assembly. I cannot pattern this.

I added a concentric to the shaft of the standoff and set it to concentric and closest.

I made another mate for the mating surface and set it to coincident.

I can't get both to mate to the holes/surface on the part. I have looked at the help and some youtube videos but I am stumped.

Advice?
