Not sure if you're located in Canada, but I've developed a Grocery List app that sorts your grocery list by aisle automatically. While it can't add items via copy & paste, if this is something a lot of people do and there is demand for it, I'd be happy to add it as a feature in a future update. My app is called Aisle Magic and is currently available for stores in Toronto.
