Proxy material ??

Hi,

Is it possible to create a proxy like material??
A method to make an “proxy” like material that automatically updateds throughout all files.

I have 100+ different files where I use the same materials.
Now it happens so now and then that a material gets updated (like client has different supplier that has a shinier finish). Now I need to open every file to update the material, or remember really good with file I have and haven’t updated.

Thanks!
