Hi P S. I wish I could give you a date of when this will be available, but unforunately, I don't have one. It is on our roadmap, and something that we will be doing. In the meantime, you could use myfitnesspal or similar programs: http://www.myfitnesspal.com/recipe/calculator. This may be an option to get you through until we make it available. Thanks for the feedback!
