How to load/unload streaming levels while editing?

I have created my own level streaming volume that works while the game is running. I want similar functionality while working in the editor. However calling UGameplayStatics::LoadStreamLevel or UGameplayStatics::UnloadStreamLevel doesn’t work unless the game is running. Is there another way to load/unload or even show/hide the streaming levels while working in the editor via C++? Thanks!

Hello all!

Up!

I doubt that’s possible but I would be very interested in such feature. Anyone has an input on this one?
