Question Create A job with unity job system to swap mesh for a custom lod system.

Hi to everyone! I am currently trying to create a job for swapping meshes for a custom LOD system to utilize multithreading. The job system works only with structs and I see that IJobParallelForTransform convert the Transform class to a TransformAccess struct to work with transforms. So my question is, is there any other way to do this, and if you are going to create MeshAccess how would you do that?
