Not related to a problem.

Describe the solution you'd like

Enable viewing of local trailers for TV shows/series.

Describe alternatives you've considered

I have tried storing the local trailer in the extras folder for the TV series, but it gets difficult if the TV series already has several extras or special features. Then anyone looking for the trailer has to 1) already know that there is a trailer and 2) scroll through any other extras to find the trailer.

Additional context

Jellyfin already has the ability to view locally downloaded trailers for movies; requesting the same functionality for TV series, if possible.
