Add Parent to Class for Mommy & Me Classes

I run several Parent-and-Child classes at my studio, and ask for parents to sign waivers as well. Since they aren't technically a student in the class according to DSP, I have to use a 3rd party for waivers for the adult and it rarely gets signed. It would be so usefull to have a feature to indicate that a class is a parent-and-child class so that we can add them to the class and make it mandatory for them to sign a waiver as well!!
