This component and the right automation would do the trick.

You cannot. I tried, I researched, I emailed… Amazon does not allow you to play your own media through Alexa. If you try to send an mp3… Alexa scolds you.

(Well, you can ask Alexa to play something from your Plex server but that’s via voice only)
