Mass Event Creation and Updating

I usually create events up to 3 months in the future, but when one event gets postponed I have to update and change the date of that event and all the events coming up. and each change would send an email about the update if I'm using the email notification option.

I would be great if I can create and/or edit multiple events and have only one email go out with all the updates.

Same with creating multiple events at once. Maybe have like a 15 minute window after saving an event or updating an event where all events created or updated will be sent in one email. But as long as the user is still working on another event, the email wont be sent. I'm sure you can come up with better idea and workflow.
