Get actor reference from persistent level

Is there a way to have a direct access to an Actor in the Persistent level from one of his sub level?
By direct reference I mean selecting the asset in the viewport, right clicking in the blueprint and having the options to "Add reference to ‘MyActor’ "

Right now I have

  • MapMain (Persistent Level)
    • Map1
    • Map2

And I want the level blueprint of Map1 to be able to have a direct access to one of the actor that is in MapMain.

I have MapMain hold all the actors that would be persistent and Map1 and Map2 would hold static assets that would need to be streamed when needed. Map1 and Map2 also holds their respective triggers for various interactions.

I could do a GetAllActorFromClass but it would be nice to be able to have access to the objects from the persistent level
