I don’t know how much you want to get into the weeds or if you even can (SaaS is SOL 
), but it turns out if you edit the JSON directly and load it back into the DB, it works a treat.
XXXDef.SysCharacter03 is the “WIP” App Studio code.
XXXDef.Content is the App Studio code once it’s published.

Make sure to compress the JSON before loading into SQL. SQL doesn’t seem to like the spaces and new lines. Also, make sure to replace any single quotes with two single quotes to escape them.
