hi @Wertandrew ,
There are two methods that have been used in past
Creative 2.0
UEFN
In both cases “Simulate New User” Edit Session/ Playtest Save and Publish.
My find was in FC2 and someone else found the UEFN versions
Next try
UEFN - Content Service (epicgames.com)
Select Project
Click your Project
Click Persistence
Click Delete to remove your Persistent data or Export for later, then reimport
In this screenshot, you can look at the persistent data live
