how to group speakers for alarm (Yonomi has sunsetted)

Yonomi has now sunsetted. I was using that app to group all of my speakers in the middle of the night prior to my morning alarm going off. My alarm is a radio station and I want to hear it in the whole house as I get ready in the morning. I have looked at IFTTT and it doesn’t look like that is possible. I have also looked at Apple shortcuts but that isn’t possible. I have Apple products only, no android. I have Alexa as well as Google at home. Any suggestions??? It is just maddening that Sonos hasn’t made this possible yet!!!
