Let's say you have a model with a lot of blendshapes from a character creator.
What is the best way to make changes to the model and also update all the blendshape sops?

Right now I'm first copying all the blendshape sops and put them above the original ones since I need the names of the blendshapes to stay the same.
Then put a reference node of the sculpt under every blendshape sop.
Then reconnect all the wires.
Then take the freeze out from all the original blendshape nodes. Why can't we unfreeze multiple selection at once btw?
As you can imagine this is a bit labour intensive with over 100 blendshapes.
Is there a way to run all the blendshapes through one ref sop but keep all the different outputs intact?
