Have MFP do the calculations from serving size to what amount you use

This, imho, is where MFP fails epically. The user must calculate the amount take to coincide with the serving size that is labeled on the product. I am more than willing to put that data in, but what I want is when I serve my portion, I put in the amount I serve. For example, serving size of Thai's unsweetened coconut milk is 0.33 cups. But I use say 1 tablespoon or 0.25 cup. I do not want to figure out what a quarter of a 0.33cup is. Or in a recipe that I make, I can put in the amounts I use to make it and how many cups it makes. But the serving size is not standard. MFP can figure it out since I have input all of the nutritional values they need. For example, I make a ginger carrot soup - onion, roasted carrots, chicken broth and salt. Depending upon how many carrots and how much chicken broth I use gives me a certain final amount. I have no idea what a serving size is. But I do know that I will serve myself 1.5 cups of it. This additional computation by MFP would be a game changer.
