Import subtitle option and viki support

I’m watching k-dramas and most dramas has no korean subtitles there, just korean audio available. I can see only export option in LLN. Would be good to have a import option with romanization support for new learners. As korean language is the main audio language there shouldn’t be any problems with korean subtitles from other sources.
Youtube has autogenerated subtitles so there no need such option above.

Viki also has learning mode but it doesn’t working in web browser, viki has more subtitles than netflix, so pls add support for viki too.

Some browser extension allows me to upload custom subtitles, but i can’t read hangul so fast yet so i need romanization option for viki and custom subtitles.
