Class Calendar specific to a class not studio wide

Would like a class calendar option specific to one or two classes; not the entire studio. We have performing classes that perform in our community. When they have been scheduled an event, it would be helpful to be able to place the event on the performing class calender ONLY not the entire studio calender. Kinda like the BAND app - where parents can "sign up" that their dancer will be performing, automate reminders, etc.......This way all information is contained in the parent portal and parents are scrambling to check the BAND app.
