When you are working on your videos within YouTube Studio, do you have any options to download the captions in either a *.srt file or a *.vtt file?  These are two closed caption file formats.  If you can download your captions as either of these from YouTube Studio, then you can simply upload that file to the same video once it has been added to your Studio library.

Do you think this would help for your needs?
