I’m curious if this feature has been added, I don’t see any info on it.
As mentioned before old prefab system was great as a placement device. This enabled artists to make large changes during a blockout stage with ability at some point to convert to instances.

Suggested Workflow
While functionality listed in this document is still accurate from a technical standpoint, Epic’s level designers and artists use following internal workflow to avoid any issues when using prefabs:
Use Prefabs as a level placement device only.
This means that once a prefab is placed in a level, it should be immediately converted back to straightforward actors by right-clicking and choosing Convert PrefabInstance To Normal Actors.
Avoid certain advanced features, including propagating actor property changes to prefab instances already placed in level, and storing Kismet logic within prefab asset.
While these features do technically work, it is possible that their use my lead to various issues. As such, Epic’s internal staff now only uses prefabs as described above and strongly recommends this workflow.
