MKV default subtitle flag

[badog]

Does Plex support MKV default flags for subtitles?

I used MKVtoolnix to set JPN audio and ENG subtitle as the default/forced for this show. Copied it to my plex server and refreshed the metadata and it seems like only the audio flag is being selected. Here is my MKVtoolnix setup

I suppose it would work if you disable Settings>Languages>Automatically select audio and subtitle tracks but I never tested it myself.
