Preview daily macros (what-if) possible food additions to diary

Problem this solves: Can I eat [food xyz] without blowing my macros? Thinking about my daily macro targets, and what I've already eaten today, how should I choose between a banana, a bowl of oatmeal, or maybe two bananas?

Sometimes I'm hungry and I'm thinking about what I could eat. I can see my macros and targets for the day in the app, of course.

What I'd like to know is what my daily macros would look like if I ate that banana. Would it push me over my targets? What if I entered 60g of oatmeal instead of 44g. How would that affect my macros for the day?

Sure, I could add the food to the diary, see the new resulting daily macro numbers, and adjust quantity/weight or delete it if needed.

But it would be much simpler to show a preview button that would compute [already consumed + proposed food]. I often use multi-add, and would like the same feature on that screen?
