Artwork change in Plex Android app

Okay. Why doesn’t the Android Plex app doesn’t have the option to change/choose poster art and background in the Android Plex app? I have to use the web app for that. In my Android phone, that’s horrible since the screen is small. I came from Emby, and Emby had the option to choose artwork within the Android app. Why not Plex? Either I’m missing something or it’s a feature that would be definitely needed. Thanks.
