Those scoops already exist and are sold at WW meetings around the states. They are expensive and you can do as described above or simply learn how to *eyeball* things using your own, pre-existing utensils. I know how much my ladle holds, how much the scoop in the sugar holds, etc. It's always a great thing to learn and good to recheck from time to time as our *eyeballing* skills seem to slip. :)
