The Hole tool's default mode snaps the hole to logical points on the geometry without a sketch, such as the center of a circular feature, the origin of a radius, etc. This is a great feature!
However, it seems like an oversight to me that if you want to do this for more than one hole in the same feature, you have to make a sketch, adding another entity to your design tree, and otherwise taking seemingly unnecessary time. If the tool is smart enough to recognize one geometry, I would expect it to be smart enough to recognize multiples at the same time.
Long Story Short: Remove the one-instance restriction on non-sketch driven Hole features.
