Suspend announcements for a period of time

[smnc]

Is your feature request related to a problem? Please describe.
Sometimes recurring events don't happen if they fall on a holiday, or events need to be suspended if the organizer is away.

Describe the solution you'd like
A command to suspend event announcements for a variable period of time, a day, a week, etc.

Describe alternatives you've considered
Manually deleting occurences of events that would fall on a holiday works for external calendar users, but is not feasible for internal calendar users.
