How to put actors from a level into another level

I have a windmill (body and wheel), both blueprint actors and in the scene. The wheel is rotated by a constraint angular motor and body and wheel are attached to the constraint. (constraint is also blueprint and in the scene). All is in the persistent level.

How can I have the windmill in a new map(level)? Say I create a new level, call it Level 1, and want the windmill in there without reconstructing it. I do not have success trying it for some reason. I did the ‘move selected actors to level’ but everything is disconnected (the wheel and the constraint) when I do it.

I too am trying to do something similar. I have actors in the persistent level that I would like to reference in sub levels.
