Most of my calendar events involve going somewhere and setting the calendar event is useless without setting the "Alert me x minutes before" calendar field so I know when to leave, but I can't figure out how to get Siri to do it. I've said stuff like "Set an appointment for x at 4pm and alert me 25 minutes before" but what it does is changes my appointment to 3:35 (I think it thinks I'm saying set the event for 25 minutes before 4pm) and uses my default alert before from that time.
