Online Store

Would it be possible to add a feature that allows us to choose our character before we go buying things in the online store so we're able to better keep track of whether the character has the items we're looking at or not? I've accidentally bought multiples of the same outfits because there is no ready indication on the site whether I had previously bought the item for said character. I know I could go through the past receipts, but with only ten items per purchase sometimes it piles up.
