Is there a better way to view trailers of the films in my library?

I do not have Plex Pass. I'd like the option to show the trailer of films in my library so family members can see if the film is something they want to see.

I have a workaround whereby I add the film to my watchlist and then the option to see a trailer is shown as well as on occasion extras.

Why wouldn't this be shown on the main library page?
