@iamsanteri there is no technical limitation to it as such. It’s another feature which might become a distraction from bigger goals. I’ve seen this popping up in the past (Duplicating a post), so have converted this thread into “ideas” topic which should give you and other users to vote on this feature. If it gains enough traction we will reconsider the priority on this 
If you have references and more details about how such feature would work, feel free to post it her. This should help making more informed decisions in the future.
