Make Last Purchased Date a Value Source
Last Purchased Date would be a handy value source to have. Say you want to shop for materials you frequently use, but you don't want to filter your groups manually. Like... you have all BFA meats in a single group, but you only actually use a few of them on the reg (say the ones for feasts, since those currently still sell well, along with a couple of buff foods). You'd like to assign a shopping operation to that BFA Meats group, but you want to filter out stuff you haven't bought in the last two weeks. Being able to filter by Last Purchased would be super handy to add to your shopping operation to accomplish this.
