Quick swap ranged weapon to off-hand weapon/shield?

Is there any way to do a mod that would allow you to quick swap say a long bow and two dual-wielding weapons from interface buttons in the bottom bar? I think you would need two off hand slots: one for a bow which would be disabled when you dual-wield (or go sword+shield) and another for off hand melee weapon/shield that would be disabled when you use a bow.
