UNREAL Engine, create instances of the scene

#1

Hi, I built a section of a tunnel in maya and imported it as a fbx to unreal engine 4. It contains plenty of objects like cables pipes etc…
Is there a way to go, to duplicate/instance the whole scene to create a very long tunnel?
I already duplicated the fbx, but it felt not right and heavy. I was wondering, if there is a better way.
