Editing materials at project level wo/ changing Library

Hello,

Currently To Edit a material I create a copy of the " Green Dot"  to Project Level, make my changes and apply to corresponding pointers. Actually replace the Green Dot Material with new Black Dot material.

I would like to not have to make a copy  every time I need to add/remove a new sheet size.  Edit Material is not an option on the Green materials. Sometimes, for whatever reason the Edit Multiple Materials screen open I changes to "Green" material are possible.
Problem is I cannot reproduce that Edit multiple window every time. I want my changes to remain at Project level.

How do you guys do it? What I am doing wrong?

Thanks
