When a designer checkout a model and work on it for a week without checking in but save and upload to his workspace there is no way to retrieve or collect that data if that designer cannot access the system anymore.
assume that the designer get serios injury and needs to be on hospital for few weeks, an admin could access his workspace and checkin all the object so that another user can continue working on them.
currently this is not possible but my customer would be really happy to have this. instead of doing undo checkout to his work, it would be nice to checkin his changes in the place of him.
