Currently, only one version of a language can be added to subtitles. For example, if you have subtitles in France French and also in Canadian French you can only upload one set and can only pick "French" as your desired subtitles when watching the video. When uploading France French, that works great; but then when uploading Canada French, it overwrites the France French subtitles.
Uploading the same video multiple times (so one version can use France French subtitles and another can use Canadian French subtitles) creates communication challenges when our internal communications team sends out only one email or our intranet team has only one page that references the video.
It would be great to be able to select multiple language versions. For example, US English and UK English; France French and Canadian French (and other French options); Netherlands Dutch and Belgium Dutch; etc.
