Tuition total per class

A way to see how much each class brings in, due to discounts and the fact that each person show their indvidual total rather than the class total, it’s impossible to work out how much profit each class is generating. It would be good to have a report, or even a box added to the class to show how much profit the class generates, to help us see which classes are working and which need fees to go up ect. Also for tax Purposes, as we are taxed differently if a class is taught by an employee rather than ourselves (this is in the UK)
