How do I export closed caption settings or add them to my theme?

We have a theme where we have defined colors, fonts etc.  We want to do the same thing with the closed caption settings.  We want to set them globally and not individually on each project. I have been able to save the Skin Editor settings but not the closed caption settings.  Is there a way to set the closed caption settings, add them to my existing theme and have them accessible to everyone.  Where are these settings stored my computer?  Can I export them and have people put the file on their computers?  We are using Captivate 2017.
