A. To manage alarms more efficiently, consider creating a routine where you set alarms for multiple passes at once. You can do this by manually selecting each pass and setting the alarm for each one. While this is not a 'select all' feature, it allows you to streamline the process by grouping passes that occur around the same time.
B. If you find yourself frequently needing to set alarms for multiple passes, consider using a third-party calendar app that allows for more flexible alarm settings. You can input the pass times into the calendar and set reminders accordingly.
