TV app: How to add show back to Up Next?

When watching a new show through one of the TV app's connected apps, it automatically adds it to the Watch Now > Up Next listings. Any subsequent, new episodes of the show will automatically show up in these listings - very useful!

However, to remove some automated listings from Up Next, I selected the latest episode(s) and chose Remove From Up Next. I inadvertently removed show shows from Up Next that I meant to leave.

After I chose Remove From Up Next, how do I add a show back to Up Next?

It seems that when manually watching new episodes, they no longer appear in Up Next.

From what I can tell, there is no way to browse my "favorite" shows that are automatically added to Up Next listings - is there?
