How to copy actors inside simulation and paste outside of simulation?

I am trying to copy a user made level and paste it to make it an official level. It will not allow me to copy and of the actors when I am in simulation (which is the only time the actors exist). I am instead, having to simulate and one actor at a time, copy the transform, go to the actual level, and paste the transform. There has to be an easier way of doing this that I am missing.
