Behavior

[Jeff13]

I have 5 categories of modifiers set up. I am trying to find out if there is a "minimum"  and "maximum"  setting as well as a "required selection" setting.

I'm having difficulty with possibly hitting the wrong modifier and then changing it to the correct one, but the first (incorrect) choice does not deselect.

I'm also wondering if the modifiers window has an auto advance. For example, after making a selection it would jump to the next category of mods. 

Thank you
