Auto multiple mates to fastener rivets

Hello

I have an assembly with some sheet metal parts fastened with rivets.

It's a top-down design, the length can change, so the amount of rivets also changes.

What's the fastest way for designin this kind of assemblies?

I used a cutout assembly operation with a linear pattern sketch driven by equations to calculate the # of rivet holes.

I supose the best way is to create a linear pattern for the original cutout assembly hole, and then use the feature driven pattern.

My final question is if is there a way to auto fill/mate all holes of x diameter?

Thank you

Regards
