[Feature]: FaceModel output in filename

[Musigreg]

Feature description

I'd like to organize my files in an easier way. It would help a lot if the face_model could be a variable that I could add to my "save image extended" node, for example.
Is there a way to output the name of face models used in an image, like just outputting text from the "LoadFaceModel" node ?

Thanks a lot in advance!
