Set "name (labell)" for "material_slot" as visuall infomation in property material window

I requested before samething but I was bad plesentator, then could not get good response. but as for me, it is important future for manage many "material sets" of object which have many "material slots"

Then give me chance please to request again. I tried to discrbe with clear reason.

When I make material for the complex object, in blender, I usually plan "material_slots" first. it is group to divide "material part" of object.

Then each "material_slots" will be assgined with "mesh faces" which I plan to group.

I can say "material_slot" is "group" to make section for material of object.

so if you make many groups, do not you name group? When we group something, usually we have clear meaning. At least about "material_slot" we have clear intention, which group are used for which face parts of the object.

Yes we can make "material_slot" as we like. that means blender have "function" to set group for material.

But the problem (and which I hope to improve) is, In blender UI, we can not see clear visual infomation, about material_slot. As human, we need "name" or "labell" then we can easy remember, manage the "group" are what for.

as data, each mateerial_slot have ID. it is ordered from top to bottom in material slot viewer. but We can not see any infomation each group are what intended for, without we clear remember "order"

I can see, "material" name. and after all, each material_slot link with material. so will you plan to use material name to group section? but "material" name should not be set to divide section of faces. actually blender official manuall, clear discribe as Tip

Naming materials

"It is a very good idea to give your materials clear names so you can keep track of them, especially when they are linked to multiple objects. Try to make your names descriptive of the material, not its function (e.g. “Yellow Painted” rather than “Kitchen Table Color”)"

I think, it is really good tip. but at same time, I feel, so how user group by function? even though I plan carefully each material_slot for "function", blender UI do not help us to set name for group.

we use vertex group, or we simply use object group. or we make key_sets, we frequently set name for them. why ? it is because manage them easy. so I request, please add option, to set name for "material_slot" to manage material with "function"

Hope this time, at least I could tell why I hope this option.
