Chair / Barstool rigging and 32-bit tuning instances

Is there any way based on this ravasheen.com/updates/1-72-28-patch-update/ that we can identify using Sims4Studio whether an existing chair / bar stool already uses 32-bit instancing?

And must we seriously create a clone of it rather than modify the original? I'm sitting on gigs of CC furniture.  I see in the latest S4S build where there is a test batch feature. I have a repository of items set up in my download / staging area that then gets transferred to folders in the mods directory.  Tedious as it would be, I'd rather set the batch fix to that staging area first, so I'm not re-introducing old / broken content later if I decide to restage, which I do from time to time.  The original zipped downloads I'd just have to identify and torch.

Edit: I have manually updated my Princess Cordelia Raised Wood Set by recreating the chairs -- sims4studio.com/thread/19655/xors-studio?page=5&scrollTo=138875

The black version I still need to do yet.
