Many of us bring lunch boxes to work. Often they contain last night dinner leftovers. Today, it is only possible to copy yesterday's lunch to the next day, but not the dinner, which would probably be more useful as most people probably don't eat the same thing for lunch every day. I would be very happy if this feature would be added as it would same me a ton of time every day. Also I think the result would be a more detailed lunch in the app, as it then doesn't matter if you don't remember every ingredient the day after or if you're just lazy, it will be correct as long as you put it in correctly the day before.
