I've been doing this. But it is mighty annoying to click so many times to get the modifiers I use most often. 4 clicks (of a page down in the drop-down menu for modifiers) to get -25 and 10 clicks to get -SL.

Shouldn't there be some way for me either to put the modifiers in order of my using them, or to simply eliminate the ones I never use and don't apply to my profession?
