Sets are designed to hold a group of drawings and their corresponding revisions. When you duplicate a drawing in a set, you have to change the tag on that drawing so Revu knows it is a different drawing and knows where to "put" it in your set. I don't know of any way to automate that. You can auto create labels when you create the initial set. But after that, individual labels have to be changed manually. If you add a drawing to a set, Revu will try and get a label/tag based on how you set up the original set and try to place accordingly.
