Feature to add multiple captions file in video

I completely understand. I seen a couple of posts regarding it on here and that this request itself is almost two years old. It would be extremely beneficial for anyone that is creating training courses in multiple languages to be able to provide CC's in different languages/ voiceovers so that they are not having to create the same video over and over. Providing the end user the option to select their required language. Hopefully this will be something that you would consider and we may be able to revisit down the line. Right now though, it's not solving our issue. Other than that the product itself is great!!
