I don't have an answer for you except for doing it the long and painful way. I'm hoping to bump this question up to a place where it's more visible.
Cimlogic had a toolbox for AutoCAD that we used years ago, and it seems SolidWorks acquired Cimlogic some time in the past. I wonder if there is an add-in that will meet our needs.
Probably not the most efficient way of doing it, but I add centermarks to all the radii & dimension to them as normal.
