Item charges texture

[mathuzzz]

Is there any way I can hide the little yellow square that bounds the charges of item? I haven´t found such option in game interface changes and can´t find the texture in MPQ neither.

you can set the charges to 0

My problem is that when charges are larger numbers, they are badly visible. I use special icons for those items, but that little square is always there. I thought it was part of the texture.
