I think you need to create a formula section. Yes we can add them in notes, but a more efficient way would to have the right section for the right information. Formula's are one of the most important part of our jobs. There should be a time/date stamp and the ability to edit. It would also be nice if it would show up when you you click on clients name from calendar. This way stylist would know if they had a previous formula. The more info we can have the better.
