[Notifications] Possibility to change notification settings with just one click

[DeteesWuber]

Problem statement:

In the notification settings, it would be nice if all notification fields could be set to the same setting with a single click. For example, you could set all fields to daily report or off, but so far you have to set each setting individually to the desired setting. A simplification in this area would be very desirable.

Proposed solution:

It should be possible to change various notification settings together with just one click.
