Siri Do Not Disturb for certain amount of time - voice control

It would be really helpful if you could ask Siri to turn on Do Not Disturb for a certain amount of time.

Why - so you don't forget to turn it back off afterwards.

E.g. - you're going into a movie," turn on DND for 2 hours"

E.g. - 2 going exercise or yoga , "Do not disturb until 3pm"

You can do it via the UI just not via Siri voice
