How to disconnect some attributes in a linking file

hi everyone, I created an animation file, and created another file for material and lighting(this is a cooperation project so i want to do it separately).

I link the outermost collection from the animation file (without selecting instance collection), and evey file is linked well.


But i can’t add or edit materials in this way!

is there a method i can link every other attributes but only materials free to edit?
Or is there a better workflow to handover?

Thank you soo much! :face_holding_back_tears:
