don’t think that is possible. Only thing i know of is if you havent saved something you can go right click → Asset Actions → reload. That will reload the file from your disc and discard any changes. But once saved i think you cant revert. I would strongly recommend using Version Control. You can check in and roll back changes with that. Best would be perforce but git also works. Here is a unreal stream if you want to get some info: Version Control Fundamentals | Live from HQ | Inside Unreal - YouTube
