I've got a toolbox that has been customized so the parts have been reorganized into folders with SS and MS versions of files. When I try to use smart fasteners I do not get any options for add to bottom stack/ add to top stack. It seems like it is only looking for the default toolbox files. If I re-enable one of these files it appears as an option again. Is there a way to tell SW that the new washer/nut files should be options for smart fasteners?
