Disable notification emails for tasks while scheduling

There are times when I take a broad look at the schedule where I will play around with tasks and dates to find the best fit, and would like to avoid spamming my artists with emails everytime I make a change.

It would be great if you could disable notifications for selected projects/sequences/shots and either have a Publish/Reenable when you are finished editing which would then send notifications of any changes.

The gantt chart is really useful except for this feature as it creates so many unnecessary emails!
