Looking to add various multi item packs with different variations

I'm looking for a way to sell my candles in packs of 1, 2 or 3 (the more you buy the better the deal)

on top of choosing the quantity I need my customer to be able to choose which candle scents they'd like

adding 3 different listings for pack of 1, pack of 2, pack of 3 isn't ideal because I need a way to keep track of quantities of the scents
