How can I favorite programs on Apple TV+?

I have searched all over the net for what I thought would be a simple question with plenty of answers – simply, is it really not possible to “favorite” a show on Apple TV+? Because, while I can’t find a straight answer, I am seeing indications that there is no such thing. One apple rep suggested that folks start watching a show so that it goes into their “up next” list and that’s how to save it. Sorry… I’m frustrated. Help please?
