Wake up based on traffic condition

Hello, I set-up the Waze Travel Time to get the time of commuting from my home to my work. On average it takes 30min and I schedule my morning Alarm on Alexa to wake me up considering 30min of communing time.

How can I change the Alexa Alarm based on the Waze Travel Time? For instance to anticipate or posticipate the Alarm with the difference between 30 minutes and the actual Waze Travel Time?

Many thanks
