Importing a max scene with multiple instances into UE4

i made a complex scene in max, It’s an organic environment for which i used some rocks, rotated, scalated and moved around to build cliffs. Is there a way to import this to unreal but make unreal understand which objects are instances so it doesnt import it repeatedly a bazillion times? (instead, can it be done so unreal only imports the rock 1 time and places copies where the instances are? That way i dont have to re-build the scene in unreal all over again) i dont want it to import it as a single mesh and lose lods and stuff…
