Scenario Planning and snapshot

Currently, we use version for snapshots. For example, create a new version for each submission, bulk copy and lock the version. However, due to size issues, we are looking for options and have heard about multiple scenarios, and snapshots. 

Wondering if there are are literatures or videos on using scenarios and how to snapshot scenarios. Also, how would we enable users to choose scenarios to different period or year via the dashboard. 

We can use the FORM in new UX to allow users create new scenario lists, but Not used to snapshotting based on scenarios and assigning scenarios to time or period.

If there is any such application (learning applicaiton) or any guidance, that would be helpful.
