Group Notifications by Pulse

Pretty much what it says in the title. Would LOVE to be able to have notifications grouped according to their pulse of origin, with options to act on (delete, mark as read/unread/snooze) all notifications belonging to a given pulse in a single click.

Reason: My team spends a lot of time clicking to delete old or irrelevant notifications. Often there are a dozen or more originating from the same pulse that could theoretically all be deleted at once.
