Here is how it works:
When a student completes the first set of lessons with Coach Carence, which is "10 hours of private lessons with Coach Carence #1." We will create another pack called "10 hours of private lessons with Coach Carence #2." Parents can easily book that new package or better yet, coaches can book the kids into the new pack and invoice or charge the parent, with their permission of course.
When Pack #2 is published, we can hide #1 so that the coach can still track attendance from the back but new people will just book #2. Once everyone in #1 has used their 10 lessons, that pack will be marked inactive. This is to avoid confusion and to ensure that there are not too many packs for coaches to track at the same time.
