Need help with copying or arraying flange holes

This is for V18 Platinum. Trying to find the least cumbersome way to take an existing hole and arraying or copying it based on a bolt circle like for a flange. My usual procedure is to push/pull a circle then arraying the cylinders followed by subtract. Tried using copyface but it seems that for "linear path" copies only. Any tips or comments would be welcome thanks!
