Spawning Actor from Class in Game - option to not put the instance in the Editor


Not sure if this is an “how to” question or a feature request.

I spawn 10000 or more actors from Class “in game”; So in the Editor I really only need the original BP version to edit.
I noticed that when I play the game the Editor will show all instances; I realize for a lot of people this makes sense to debug.
However I worry about the overhead for my project in the Editor. Would it be hard to make this “optional”? …or is this function allready working?

…or is the “overhead in the Editor” not really a performance issue?

Thanks for your help.
