Re-import Revit sheet from DWG

Hi everyone. I come again with a problem. I don’t even know if it is possible to solve.

I have exported a DWG from a sheet in Revit with a lot of Views to let another Planner extend it with his details. Now I want to import back his work in Revit finding that I have to split the DWG in several files and align it manually in every view.

Does someone have a better idea how to solve it? Is it possible to make Revit recognise what it exported and aligns it back?
