Prefab Tool brings nested prefab support to Unreal Engine.

Prefab Tool Youtube Playlist

It allows you to convert preconfigured actors in the level to prefab asset in the content browser, and then add the prefab to the same or other levels as many time as you like. 

Prefab can be edited in the level editor directly, all changes to the prefab can then be propagated to all existing prefab instances.

You can disconnect a prefab instance to prevent it being automatically updated by prefab changes. Or you can choose to revert any changes to the prefab instance.

Prefab can be nested to support complex scene hierarchy. Changes to nested prefab can be reverted or propagated like normal prefabs.

Prefab is an editor tool to help level building, it can't be spawned in runtime. Once prefab instances been placed in the level, you can choose to convert them back to normal actors.
