How to rename/remap blendshapes for FaceAR?

I have to use skeletal mesh where the blendshape-names are different from the names necessary for FaceAR.

The documentation for FaceAR mentions it, but I can’t find anything on how to set it up when the names are completely different. There’s only this hint to append additions to names:

That’s all I can find.

I don’t want to append names but map completely different names for all the blendshapes.

Any Idea on how this could be done?

I’ve got the livelink asset as suggested in the documentary.https://docs.unrealengine.com/en-US/Platforms/AR/HandheldAR/FaceARSample/index.html

But I’m looking for the right node for actually remapping the names. Or maybe I need an external list of some kind?

I also asked that question here:
