It would be helpful to be able to add a file to more than one task/project/folder. Instead of having to copy it to multiple locations, being able to tag it to more than one place would be helpful like you can with projects/tasks and folders. That way you don't end up with duplicates or have to remember which location has the most current version. It would also preserve any comments/proofing notes tied to that specific file. Is there a way to do this that I'm missing?
