Alarm that Shuts Off Automatically?

I’ve only just downloaded SAA, but I can’t seem to find a way of making the alarm just play an mp3 once then shut off automatically. I don’t want to have to shut the alarm off at the phone. Is there any way to do this?
BTW I’m also using a bluetooth headset, which appears to stay connected OK if I force the alarm to bluetooth feature.

Hello Andy, you can set an timeout on the alarm … the minimum is 1 minute… than please also play attention to the backup alarm option… you may want to make it silent… what is your use-case?

Thanks Petr,
unfortunately I want the alarm to sound for literally 5 seconds or so, then go quiet on its own without my having to do anything. The use is as a way to wake and attempt a DEILD, which means not moving at all.
