TMM: TV Series

Is there a possibility to have the logo, poster, banner and so on only in the root of each series?

I would like to have fanarts and so on only for the series but not for each episode (in subdirs S01, S02, S03…).
In the subdirs I want no other files than episode1.mkv, episode2.mkv, episode3.mkv and so on.

Thank you in advance for your assistence and advicesSmile
