I often buy bunch of formations with single, double, whatever units then buy whatever is expensive and finally a number of lower value units then go back and delete the initial single/double/whatever and buy whatever I actually wanted. If I have to many points and get more units then I wished I rebuy the placeholder and add another low value or three unit at the end. If I don't have enough points I'll delete sufficient low value units at the end till I do. Then delete everything you didn't really want after your new "correct size" formation and continue on.
