How to give a Metahuman 2 different eyebrow colors?

I’m trying to give each of my character’s eyebrows a different hair color. I tried exporting the eyebrow mesh (LOD0) and taking the FBX into blender so I can separate the meshes, but when I try to apply that to the eyebrow groom in editor, it didn’t seem to really work.

I’m kind of at a loss of what to do and I would really like to avoid having to make the eyebrows from scratch…

Any suggestions? Thanks!
