In previous versions, one could open the current policy, make 50 changes and then save it with a different name (usually, firewall.name.date). If there was an unforeseen issue (or management decision), one could rollback easily the old policy by installing the old version where everything was working as expected. How do you handle this situation in R80? I'm not seeing an easy way to save the current policy under another name to have a way to perform change management/revision control and restore it.
