Ability to set audio output source for different alarms

[jhahn35]

First, thanks for the extension and made it available for free!

I often listen music/background noise while using the alarm, but during the break, the alarm sounds to my headset, so I don't get to hear, so I would like to set audio output source (or conventions/rules), so that the break alarm can be fed into my speaker rather than to my headset. Thank you!
