PLAYER PACKS

Maybe this is already possible, if so please let me know. We do dozens of sports teams and offer something we call “PLAYER PACKS”. It normally offers 3-4 items in a just one sku (i.e. HOODED SWEATSHIRT, T-SHIRT and SWEATPANT). What I need for this ideally is to be able to offer the 3 different items, but with the ability to plug in sizes for each specific item offered in the pack. See photo below for what we would commonly offer.
