Why can't I set shift + mousewheel up/mousehweel down to scroll hotbars? Would be helpful as a hybrid class like Red Mage where I goes cast to meelee to cast.

Also, can I make hotbar scrolling ignore empty hotbars, like hotbar 3-10 for me, so I ONLY scroll to hotbars 1 and 2 regardless of which way I hotbar-scroll (up or down)?
