How to export baked BlendShapes Animation without Mesh?

Hello,

I have a scene In Maya where I export the Skeleton Mesh (joints & geometry) and the Animation (baked joints) in two separate files, which works fine. However, the only issue I’ve come across so far is that the animated and baked BlendShapes are not exported in my animation. In the SkelMesh they are there, but in the animation the values are missing.

Is there a possibility to export the baked BlendShapes without the mesh (just the animation)?

Thanks.
