Alarm config question

view story

http://forum.xda-developers.com – My fiance just got the SIII upgrading from the Incredible 2 and she loves it. I love it too as I no longer have to hear about the degrading performance of the I2:p. The only complaint she has is that her work shifts are always changing and with the alarm on her old phone it would default to "only once" when you set it each time which is exactly what she needs. The built in alarm on the SIII requires you to set the exact day each time you set the alarm. Is there anyway to have the built in alarm go to a "only once" type alarm vs having to set the day each time? (HowTos)
