To publish new episodes to YouTube, first you'll have to connect RSS.com to a YouTube channel. Once your account is connected and has the right permissions, you can start publishing new episodes to YouTube.

When publishing an episode to YouTube, you can choose a playlist destination.

By default, the videos will be uploaded to the YouTube channel. However, you'll have the option to select a playlist where the video will be published. 

The available playlists will be listed under a dropdown menu. 

By default, the "none" option will be selected, but you can choose another playlist and the selection will be saved automatically. 

The changes only affect the episode that are going to be uploaded in the future.
