Closed caption translations

I notice this thread is a bit dated, but I'm not finding anything newer. Is it yet possible to have closed captions for multiple languages in a single Storyline course? As a native feature (I don't think the inventive Javascript hack will work for me).

We need to deliver compliance courses in several languages (4-22 different languages, depending on the course). For some, doing voice over in 1 language and closed captions in all the others is the best option for budget and timeline. Creating a unique version of the course for each language, uploading all of those to the LMS and getting each assigned to the correct audiences - that's a lot of work. Would be sooo much easier to upload multiple srt files to 1 course and allow users to choose their preferred caption language. Is this an option?? In Storyline or another of the products?
