Have some filtered DE's from Synchronized DE's. I need to test these audiences and would like to create filtered/duplicate's for testing as a snapshot in time to test. The issue with these filtered DE's is they are created using a long set of automations and update daily causing them to not be testable due to requirement of static DE's.
Tried:
Unable to create DE from existing (these filtered DE's don't show up in their folder when doing this process)
Unable to do the simple create copy from Contact Builder under these DE's (option not there)
Other than setting up the complex automations that make these to run only once, is there a solution?
