Allow auto-pause on the second subs language

I am using now your - amazing - extension.

I am studying the second subs language.

Watching an English movie with Thai subtitles below the English to study Thai!

But the auto-pause has only one option to stop after every line of English.

I know that if I am turning my whole settings around (and getting a much more limited set of movies) I will be able to put English below the Thai and fix this.

But can you add an option to change the auto-pause on text lines of the lower language in the subs?

Additionally, if you can adjust better the app for people like me, it would be wonderful!

thanks a lot
