Specular highlight per Material in the Viewport(Solid Mode).

If it's possible to have Specular highlight per Material for Solid mode, I want to represent each material characteristics in the viewport..the issue even when making the material 100% roughness there is still some highlights overlay on top of it, it's until disabling the global option you get the desired look, so if it was per Material it would be much easier to set it up.

Example of the problem.
