Allow "Don't Send Notifications" on Topics and Tasks in the Team Notification Settings

Right now, on the top right of any team there's an elipsis.  The first option is "Manage Team" and below there's "Notifications".  There, you can chose 3 options for Topics and the same 3 options for Tasks:

Topics/Tasks: 
- New Topics/Tasks created
- New Topics/Tasks and replies (auto-subscribe)
- Only Topics/Tasks I'm participating in

I propose a 4th option: "Don't Send Notifications".  Especially for Tasks.

When you have a small team and few tasks, it's not a big deal to create a Task and be "Auto-Subscribed" to it, so every time there's a reply you get a notification.  However, if you create a lot of tasks for your team and you trust your team, you really don't need to get notified every time there's a reply.  Actually, you can get too many notifications which will clutter your notifications stream.
