Rounding corners only on outside corners?

I know how to use the live corners tool on all, or selected corner points, but I am looking for the option to apply the desired corner radius on either all outside corner points or all inside corner points of a selected object or set of objects. 

For example, a star has five tips and five inside corners. On a star, I can turn off all of the live corners, then manually select only the five tips to use the live corners. 

I had been working on a font with roughly 200 characters and wanted to add the slightly rounded corners to all of them at once. I didn't see how to do it in Illustrator so I opened the file in a sign design program on my PC and did the job with one click: "round outside corners" at .02" radius. I have Astute Graphics on my Mac. I watched a lot of videos there, but don't see the option.

Any help would be appreciated.
