As part of the notifications applet, the options for Do Not Disturb are
- 1 hour
- 4 hours
- Until evening
- Until next morning
- Until manually disabled
How could I add my own times, say, Do Not Disturb for 2 hours, without manually turning off the DND mode? Also, is there a way to add an option which asks for a custom duration? (Essentially the same as “Until manually disabled”, but not requiring the “manual” part).
