Meta Humans Topology

Guys, currently, is there any way to bring modified Metahuman mesh to UE4 while keeping the rig? I can easily apply some simple adjustments in Maya (like enlarging the nose), no change to topology, and the facial rig seems to keep working fine. How can I bring it to Unreal? As a morph target or just an updated skeletal mesh, but to keep all the rig? (currently the rigs mismatch if I export from Maya and can’t use the existing MTH skeleton).
For me and for sure many other it’s the biggest feature request!
