How To Get All Actor Across Level Stream

Hello Guys i’m making a horror game map,and using level stream but i’m stumbled for days on this problem:
A.How to get all actor of class from all level stream,i want to access it from my persistent level,no matter that level stream is active or not i want to get all actor from it level stream,which i cant get it from Get All Actor Of Class (What i’m trying to reach here,is i want to spawn specific actor at specific place with specific amount,for example i want to spawn fuelcan on drawer actor,but i want to spawn it randomly across all level stream).

If there’s another way to do it,please tell me.All Answers Appreciated,especially if it’s using blueprint,because i’m very newbie at C++,thanks.
