I want to achieve the following logic:
1. From the first screen of show details (at left), the user will click on add to my schedule
2: An alert dialogue pops up with the option to choose from 2 dates (Premier or Replay) and click Save with the chosen time and date.
3. The show will be stored in a subcollection called mySchedule
4: The show will appear in the user calendar with the selected date.
5: The user get notified before the show start (15 minutes).
