As a quest/pathway creator I want to be able to fork some other quest/pathway and build upon it

A rich environment encourages people using it to create more. So the idea is to let people stand on the shoulders of giants by employing a forking mechanism. Say, Sandbox has created some cool quests to onboard people to its metaverse, now Alice tries the collection and falls in love wishing she was able to take this as a template for her own work.
