How can I make it so that the priority only setting is retained? I always want my alarm to override.

[AC Question]

I go to the Do not disturb section of settings and and select "priority only" then select "until turned off", but then the next time I cycle through the sound, vibrate, and do not disturb, it erases the setting! Is there anyway I can make it so that when do not disturb is on, it is always on priority only? I don't want to have to go into settings every night in order to select "priority only". Thanks.
