Any way to blur the subtitles AND translations?

I like using this extension when I’m working on intensive listening, my only issue is I want to have the ability to blur and unblur the subtitles AND translations as I’m watching a show. I tried turning of the main subtitles, but then the problem I ran into is that I could no longer loop lines of dialogue. I’m trying to train my ear, and having the subtitles in the original language in front of me makes me occasionally “cheat” and read instead of listening. I want to be able to press a single button to see all the translations and the subtitles at once when I can’t piece together what is being said through my ears alone.
