Multiple captions in one storyline file?

Hello everyone,

I am facing the same issue as we need to publish subtitles in 3 languages for all our audio and video files included within Storyline. I was about to use the layers workaround suggested in this thread but I have an issue: when there are already several slide layers added to a slide this doesn't work. Because if I tick "hide other slide layers" on my previously added slide layers then users can no longer access the audio and captions in my language slide layer. I cannot untick it because otherwise all objects from all my slide layers show up on screen.

So I am looking for a solution to have three different subtitles languages available for audio/video when there are already several slide layers with visual objects added to the slide. Can anyone help?

Thanks in advance!
