Typically my clients are booking more than 1 class at a time. So lets stay my client booked 6 classes (different times), and then they change their mind on 1 or 2 of them and cancel those classes, im getting notification. However, notification details include the classes that are still on the books but does not mention which classes got cancelled. I like this notification to only let me know which classes got cancelled. How can I make this happen? Please help.
