Add nutrient comparison for 2 foods

Hello,
quite often I am trying to compare 2 foods and how they fit into my nutrition score.
For example I add 7g of chia seeds and flax fleeds, I select one to see how much micro/macro one adds, then select the other and go back and forth to see the difference.

It would be very, very helpful if I could select one (or more) foods, then select another and compare the two with the quantities I inserted
