Feature request: Ability to set a wake up alarm based upon Body Battery value like 90% or 95% or 100%.

I have a Forerunner 265 and love it.   I use it to track my Body Battery.   I'd like a way to set a wake up alarm that turns on when my Body Battery reaches 100% or some settable value like 90% or 95%.    
Conversely I'd like an alarm that vibrates when my Body Battery reaches a settable low value,. e.g. 20%, that indicates it is time to go to bed.
