importing embedded thumbnails

[Nik0s5]

I want to migrate my video archive, but there is a problem - some video files have embedded thumbnails, but Hydrus Network does not take them into account, creating its own icons.

For example, the video was downloaded with --embed-thumbnail applied:
yt-dlp -P Y:\123 --embed-thumbnail <URL>

You can extract the thumbnail like this:
ffmpeg -i 123.mp4 -map 0:v -map -0:V -c copy thumbnail.png

Is it possible to add to Hydrus Network the ability to import embedded thumbnails if there are any in the video?
