[Mesh Importing] Multiple collision meshes are not imported correctly

Unable to import multiple collision meshes in a single mesh from Blender. They either get imported as standard meshes/visible geometry, or get merged with another geometry of the same type (_col, _sph, _tri). Renaming them to a scheme like 'Mesh_lod0'; 'Mesh_lod1'; 'Mesh_lod2', as in incremental numbers as separate meshes don't work either (nor keeping them as .001, .002 and so on.

Steps to reproduce the behavior:
1. Export a mesh with multiple collision meshes

I'm using `environment\decorations\ships\basic\geralt_boat\meshes\dest_parts\boat_base_mesh_pile.w2mesh` for this example

2. Open it on Blender
3. Scale the collisions meshes to 100x (as per my previous bug report)
4. No matter what you do when reimporting, it will not reimport all of the collisions meshes as proper collision or it will merge them.

A solution for importing multiple collisions meshes from blender would be great. It does it correctly from Maya, but Maya has its own set of issues.

Reproduce with environment\decorations\ships\basic\geralt_boat\meshes\dest_parts\boat_base_mesh_pile.w2mesh by opening it in Blender and reimporting the exported asset. Compare how multiple collision meshes are classified, merged, or exposed as visible geometry. Done means the separate collision meshes import correctly without merging or becoming standard geometry.
