Inactive Students vs. New Students

Hello, I would like to see anoter section on Dance Studio pro with Inactive. I have some parents that have quit dance and the new enrolled students are inactive until they select a class and decide to join us. I would like to seperate the two. It would be nice to have new accounts created or new intrest and past students or something where the kids are seperated. Different types of communciaton goes out to each group if they were a way to seperate them it would be easier to manage. Thank You
