Please improve/streamline the process of displaying recipe nutritional data edits

I'm developing original LCHF recipes for some friends and I. The way that carb manager adds ingredients, and displays the nutritional data, is incredibly tedious.

If I want to see the carb count after add tomato paste to a recipe, I have to open the recipe> edit> add/change ingredient> save> open recipe

A huge improvement would be if when adding an ingredient the nutritional data on that screen was divided by the portions, and not given for the full measure. Or simply add the macros to the edit screen, and not force us to save it, and open it again.
