How to refresh TV Shows (forced) metadata individually from command line with Plex Media Scanner?

Hello,

I’d like to ask you for some support/help regarding Plex Media Scanner.
I want to refresh my TV Shows (TV Show folders) to be able to download subtitles (which aren’t available as soon as the new episodes released) to them. My problem is, that I have a quite big library with TV Shows in it (5-6 Seasons in some cases) and I don’t want to refresh all of the TV Shows metadata every day to avoid ban from Google where my contents are. Some TV Shows also ended so there’s no reason to refresh them for new subtitles every day.

My question is, that it is possible to run the Plex Media Scanner in such a way that the metadata are forced to download (at least the subtitles) but not for the whole section, but only the TV Show or the TV Show’s actual season?

I tried some Plex Media Scanner switches but it seems, with them the scanner only scans the newly added episodes and skips the older ones, so the trigger for the new subtitles is missing.

My scanner examples:
/usr/lib/plexmediaserver/Plex Media Scanner --scan --refresh --section 6 --directory /home/user/…/Series/Fear the Walking Dead/Season 03
/usr/lib/plexmediaserver/Plex Media Scanner --scan --refresh --section 6 --directory /home/user/…/Series/Fear the Walking Dead

It forces the metadata download for the whole section (and I want to avoid it if it’s possible):
sudo su plex -c "export LD_LIBRARY_PATH=/usr/lib/plexmediaserver && /usr/lib/plexmediaserver/Plex\ Media\ Scanner --refresh -x -c 6

Could you please tell me, how can I use the switches to trigger the “Downloading metadata for…X”, where X is the current episode (or to simulate the Refresh button for it?

Thanks in advance!
