During it, he pointed me towards Artisans of Vault video on how he does it, using pose brush and UV mask trick.
I used to manually paint face-sets for this purpose, to use the pose brush in this way, however I think the Mark-Seam, Face-set-initialize using UV Seams will be significantly faster in certain applications!
