If I make a pocket with a complicated shape and lots of corners, is there an easy way to fillet all of the inside corners other than selecting them all one at a time? I don't want to fillet the bottom edge of the pocket, only the edges coming up perpendicular to the bottom, and only interior corners, not exterior.

To me the ideal interface would be to select the bottom surface of the pocket and have some option for Fillet Perpendicular Edges, and then some other option for interior angles only (sometimes you might want to fillet exterior edges too).

I know I can't be the first person who ever wanted to do this, because this is required to make a pocket machineable. I know I could do sketch fillets but that still requires selecting each corner individually, and often times I think it is cleaner to have the fillet as a separate feature.
