Increase DURATION for all alerts

I know this has been hashed before, but I can't seem to find the answer.

How can I prevent hobbit from sending alerts unless the test has been down for 15 minutes (or some time) without using the DURATION tag? I seem to be putting DURATION>15 in all alert rules, so I am looking to set it globally.
