Set backup alarm individually for every alarm

As of today, the backup alarm feature can only be set globally for all alarms. I’d like to set an backup alarm individually for each alarm that I have. Not every alarm is meant to wake me up. If I want to use Sleep as Android for a multitude of alarms, some of which are silent, I have to disable backup alarms entirely. So either I lose a feature completely or I have to use other alarm apps.

Please put the settings for backup alarm with the settings you can change for every alarm, similar to alarm tone settings.
