Increase texture specular but not from specular column

[astroNOT 260]

Hello,

I'm keen to know, is there a way to increase a specific item texture specular (weapon/armor/etc) beyond the 100 that you can set in specular column? 
Or better yet to edit the texture to define what 100 specular should be.
Point is, some items aren't as shiny as they should be at 100 specular

PS. I assume the specular is tied to the texture.

Thanks!

Specular texture is just a white texture applied to the original texture with opacity level equal to specular level. That means even if you increase the specular level it will be the same (Those 100 points in Specular column mean 100% opacity).

The correct way to tackle this issue would be editing alpha channel of the texture which impacts area of the shine and it's brightness.
