[BUG] Re-import static mesh issues

So I’ve created a scene in 3ds Max of a tree model with 2 LODs, Vertex Paint and two Collision Objects.
When importing the mesh the first time, I checked all of the boxes in advanced import options; textures, materials, lods etc. The problem is I realized I accidentally made a mistake with the collision objects intersecting so I adjusted them and selected re-import on the static mesh. Sadly this re-imported everything and made a duplicate of all of my textures and materials and re-assigned these new materials to the mesh instead of my tweaked ones.

Is there no way to enable some sort of intelligent re-importing where it only re-imports the parts of the scene that have changed. Or even the option to ONLY re-import certain parts of the scene like the LODs or Collision?

Thanks!
