I often set multiple reminders for a single calendar event, and the reminder banners accumulate and don’t disappear on their own after the event is over. It gets very messy on the Lock Screen to have, for example, 5 banners for Event A (past) mixed in with 3 banners for Event B (future), and I have to manually sort through them to dismiss only the Event A banners.

I would like (1) an option for the newest Event B reminder banner to replace any older existing Event B reminder banner, and (2) an option for banners for past events to disappear on their own without manual action.
