Set the sheet set manager to allow layouts to be added to multiple sheet sets. In our industry, when creating permits we have some layouts from a single DWG that we need in multiple permits sets(Sheet sets). Currently if the Sheet set manager knows the layout is apart of another sheet set, it won't allow us to add the layout to our current sheet set. We would have to move the previous sheet set to another location to break the path AutoCAD remembers and then add the Layout(s).
