Create a podcast station on Mac
You can create stations with the podcasts you subscribe to—for example, you might want to group all podcasts about personal finance into a station. You can play the podcasts in your station in any order, and the stations are automatically updated when new episodes become available.
A station has the station icon 
next to it.
In the Podcasts app
on your Mac, choose File > New Station.Type a name for the station, then click Save.
Update any of the following station settings:
Station name: Type a different station name, if you like.
Play: Choose what order the podcasts in the station play in.
Group by Podcast: Turn on to organize the station by podcasts.
Episodes: Choose which episodes to include in the station.
Media Type: Choose whether to include audio podcasts, video podcasts, or both.
Unplayed Only: Turn on to include only episodes you haven’t played yet.
Choose Podcasts: Choose the shows you want to include in the station or choose Include All Podcasts.
Click Done.
The station appears in the Stations section under Library.
Once you create a station, click the More button 
in the top-right corner to play it, delete it, or change its settings.
