Feature request: copying food for day of the week

So, you know how you can copy food from the previous day? The problem is, I get very bored of the same food every day. And I have routines where I go out to eat with friends every Tuesday and Friday. So it would be great if I could “copy last week” instead of copying the previous day. That way I could work on making little changes in my diet each day without having to completely rewrite my routine every day, but also not have to eat the same thing I ate yesterday. Does that make sense? I hope you will do this. Thanks!
