Thanks for your question!
The answer to your question is yes – you can do this as part of a routine that opens the radio station skill.
To begin with, open the Alexa app, go to “More”, then “Skills” and search for the radio station you want to listen to.
Once you’ve enabled that skill, go to “More”, then “Routines” and create a new routine. When it comes to the action step, select “Skills” and then pick the Radio Station Skill you previously enabled.
Make sure you set the Routine to run Monday through Friday only!
Hope that helps!
