Does Timely app have a way for the alarm to stop after so many minutes?

[gwa000]

Have the Timely app installed on my Google Nexus 7 (2013 version) and running version 6. something.

I have set up an alarm to go off at 10PM.

Is there some option/setting that I am just not seeing whereby the alarm will shut off after a specified time? From what I can see is that the alarm just keeps going on which is not ideal if I am not in the vicinity of my tablet.
