statements by family instead of by individual students

We calculate tuition by total number of hours per family. We don't break it down by kid. So it would be great if there was an option for the system to just send one statement per family instead of individual statements per kid. It's confusing if one kid takes one class and the other kid in the family takes three classes, but the statement amounts are just split equally. (i.e. $50 on each statement for a total of $100)
