Skyrim mouse wheel to change magic

so i never have played any of the elder scrolls games, so i got skyrim and have been playing it for a while, but its so annoying having to use my inventory to change my powers, weapons, magic etc. since my all 8 of my hotkeys are full. is there a way (modded or unmodded) that i can use my hotkeys to select a type of weapon/power, then use my scroll wheel to change between those things in that category? for example press 1 for destruction magic, and then use the scroll wheel to change between fire, frost and shock.

also, i have remapped my zoom to the arrow keys since i always play in first person
