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:

https://docs.unrealengine.com/Images/Platforms/AR/HandheldAR/FaceARSample/LiveLinkRemap.png

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.Face AR Sample | Unreal Engine Documentation

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

Hi,

I’m sure there’s a better way of doing it, as this is very time consuming…but it does seem to work.
I’m currently trying to do the same thing with Reallusion characters
