Let’s say you have a building with 20 separate parts; you export them all, then import without combine meshes selected. Then drag one part into the scene and set it’s location coordinates to 0,0,0, and do this for the rest of the meshes. They will all be placed at where they were in your modeling software. It can be cumbersome sometimes, but maybe a solution can be found via plugins or Blutilities in the future.
