Google-calendar – Any way to Add a reminder more than 4 weeks ahead of a Google Calendar event

There doesn't seem to be any way to get more than 5 notifications for one event in google calendar.

One workaround that may be useful is to create two (or more) events starting at the same time as the event you (really) want to remember, and then add five reminders to each of those.

You can't select which calendar in Quick Add. However if you add event by clicking on your calender grid, you can bring up a dialog which allows you to select your calendar. That's pretty quick to me too. E.g. I can say "@7am dentist appt", then select a calendar, then submit, this doesn't go through the full calendar configuration screen.
