Centermarks for polygonal holes

I design conveyors using long patterns of polygon holes. What is the easiest way to create centermarks for the holes in the drawings? Currently, I use the center line tool and create two centerlines and then use the grip points to try to make them as centeredsas possible. I need somethiung easier. It seems like this would have already been an added feature. Am I the only one that thinks this would be a great idea?
