How to setup automatic LODs inside Unity?

### Describe the bug 💬

Is it currently possible to automatically setup LODs inside Unity in a similar way to how fbx does it?

For example exporting a fbx with 3 objects named ..._LOD0, ..._LOD1, ..._LOD2 would automatically setup an LOD group in Unity.

An example for the workflow to do this with Blender would be helpful.

### Steps to reproduce 🔢

1. Export mesh with LODs from Blender
2. Import into Unity and automatically setup LOD Group

### Validations 🩹

- [x] I have [searched existing issues](https://github.com/KhronosGroup/UnityGLTF/issues): no issue already exist that reports the same problem.
- [x] I follow the [Code of Conduct](https://www.khronos.org/about/code-of-conduct)
- [ ] I provided a [minimal reproducible example](https://stackoverflow.com/help/minimal-reproducible-example), including files when necessary.

The issue names no files or tests. Start by tracing UnityGLTF's editor import workflow and comparing the requested LOD0/LOD1/LOD2 naming behavior with Unity's LOD Group setup; done means imported LOD meshes automatically produce the expected LOD Group, with a Blender workflow example if supported.
