STM32F4xx RTC questions

First, I have been able to "setdatetime" and "getdatetime" using excellent example code. In fact, I wait until after powered up to receive a "setdatetime" command (via UART). Using the HSE on F4 Discovery board (presently LSE is not populated), I was able to see only a 5 second deviation in 16 hours of run time.

Is there a way to set the alarms independently of the date and time?
For instance, can I create a "setalarm" command that would do this? 
Or does everything RTC-related need to be initialized at the same time?
