Mesh Merge Morphs Not Transferring

I’ve read a lot on this and there’s little to no documentation. I’m wondering if anyone has successfully merged meshes together through UE4’ SkeletalMeshMerge system and was able to transfer morph targets from the unmerged meshes to the fully merged mesh.

I’d be interested even if it didn’t merge over nicely such as it bends the model in weird ways currently I either crash because it didn’t make it all the way because something was missing or it works but the model doesn’t change and i can see that setting the curve doesn’t activate the same functions editing the morphs in Editor do when you’re previewing a mesh and it has the weight list of morphs.

Even if you can’t give me a full answer for any specific reason even a direction might be useful because my direction just hasn’t been working.
