Auto snooze notifications after motion detection

Please can we have a setting that will stop notifications for a chosen length of time after a notification. If I walk into the garage and I get a notification that is fine, but I don’t want to get another one two minutes later when I am still pottering about in there, repeat again and again. I would put the setting at about 30 mins, so after the first alert I know I would not be notified again for another 30 mins.
