Auto shut off alarm S6?

[AC Question]

I just upgraded to S6 from S4 and I'm used to the S4 alarm that auto shuts off after a minute or so. My S6 alarm keeps going and going and going. This is annoying because I use the alarms for waking up but also as reminders or cues for my toddler. Ie: Time to brush teeth and get ready for ed. I often don't have my phone in my pocket and the alarm would go off then auto stop and I wouldn't have to worry about it. Is there anyway to make the galaxy s6 auto shut off the alarm?
