Sometimes Assets objects can be duplicated inadvertently (via import or some other means) and the duplicate objects to diverge as users update one or the other, being unaware of the duplication. As of right now the only option is to update one object with all the changes that were made to the second one, and delete the second one. It would be helpful for users if there were a way to merge two objects together in Assets so that duplicates that have diverged can become one object again.
