batch processing of material is required

Describe the project you are working on

ordinary RPG game

Describe the problem or limitation you are having in your project

if i select multiple materials and change the values, only one material value changes.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

multiple material values and be changed simultaneously.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

.

If this enhancement will not be used often, can it be worked around with a few lines of script?

.

Is there a reason why this should be core and not an add-on in the asset library?

if there is no improvement, there is the inconvenience of having
to change various material values dozens of times repeatedly

Moving to discussion, as there is no concrete technical implementation provided.
