Is there a way to change the overall interior coordination proposal as a set?

I have a question about the extension’s material color picker.

Not a single object
Is there a way to change the overall interior coordination proposal as a set?
I want to change multiple materials at once.

If it is not possible, can the script handle it?

Thank you.

The material picker doesn’t support changing multiple materials at once.
