Show Blu-ray cases only for external media?

Is there a way, in the Showcase view, to have Kodi show Blu-ray cases for external media only? I’d like to have the extra visual indicator that the movie is on physical media, so ideally it would show movie posters for digital files and DVD/Blu-ray cases for physical media based on the naming of the stub file: Movie Title (2011).bluray.disc, Movie Title (2007).dvd.disc

Windows 10, Jarvis, Aeon Nox 5 Silvo if it matters.
