Import OBJ with same vertex count into Layer

Since no software I’m aware of except maybe Nomad will export mesh data to GLB as quads, it would be helpful to be able to import an OBJ file with a matching vertex count, into a layer (vertex order on import would need to be maintained). OBJ itself does not support layers. FBX and Blend formats do, however, I think it would take more work to implement those formats.
