An event is set for, say, 3pm-4pm in my pre, with a 15 minute before reminder.

If a meeting goes longer than expected, and I can't check my phone between 2:30pm and 3:15pm, then by the time I finally get a chance to check my pre, the event has already expired and the pre either does not show me the notification, or only shows me the notification once and then clears it (even if I press "Snooze")

Is there any way at all to make calendar event reminders STAY active until I have dismissed them (even if it's 24 hours or more after the event has ended)?
