Blueprint: Move in box load a level appear in new box in new level and go back again

I’ve got a elevator when I move to it the doors open I get in and it fades to black it loads another level and I appear in another elevator in the new level. Thats all and it’s fine but now I want to be able to get back in the elevator and appear in the other level again? Basically I want to be able to go in and out of the elevator to switch between the levels.
I could do it with a physical button but I rather not.

Any Ideas?

Thanks!
