Not enough 3/4" knock-outs in 40-position panel

My 40-position panel does not have enough 3/4" knock-outs. Why not 40?
Do I have to Greenlee punch more?
Greenlee punch size?

Why do you need that many 3/4" KO's? You can normally fit two NM cables in a 1/2" KO.

Yes, you can use a 3/4" (trade size) Greenlee punch to make the holes larger if needed.
