The Subscription Reorder - Lock Menu panel on the subscription page (and on the customer's My Subscription page) lets you pin, per delivery weekday, a past delivery date whose included meals should be repeated. Each weekday card shows either Random Meals or the pinned date with its meals; click Click to Change, then in Select Date for <weekday> click Select next to a date (only dates that had included meals are listed) or Random Meals to unpin. From then on, whenever auto-selection fills that weekday it reuses the same meal for each slot when it's still on the new menu and still passes the customer's allergen/dislike/category filters; if not, a random pick is used instead. Customers can change their own locks from their profile.
