groom_root_uv to Unreal

Heya Guys. Seems there is no option to apply our blender textures to alembic groom from Blender to Unreal. Seems thats the groom_root_uv function is missing in the export so the UV's are sphereised. Not sure if it's never been developed or missed but would be great if it could be looked at. Anyone got experience with this?
