I understand that there is a feature request that is likely to be available soon allowing users to set different alarms/reminders per calendar entry.

However, it seems that what I am looking for is a different feature.

How can a user set a reminder time other than the pre-defined options of: 1, 5, 10, 15, 30, 45, 60?

I'm aware that I can set this using:

zmprov ga <user> zimbraPrefCalendarApptReminderWarningTime <delay>

But this isn't very helpful for the user. Furthermore, the UI displays "never show" under Options -> Calendar, which is very confusing.

Is there an easy solution to this issue, or is this a feature request?

My users want to set reminder times up to 1 week in advance of appointments.
