Cover and Trama for any folder name in all add-on

Hi,

i have kodi 17 in my rpi3 with deafult skin estuary.

I use an add-on to have access at my cloud nas.

I need to know if is possible have cover of fanart and trama for all folder, that have the name of tv show, like Lost, and subfolder Season 1 etc... but also for movies. ( when i select a movie or a tv show without play, i wish to see trama and cover or fanart. )

I have ExtendedInfo Script, but i guess that doesn't works inside any add-on.
