I want to create a language menu page for a course that has been translated into various languages.

I want to create a language menu page for a course that has closed captioning translated into various languages. I don't want all the languages in one zipped file because it will take too long to open. We use an LMS that is complicated to use and we don't get much support on it, so I am looking for a solution in Captivate. I have explored options using Adobe Multi Sco Packager, but I haven't figured out how to create a menu page. The answer seems to be in the question thread for "Landing page for translations" but I don't know how to make it work. I need more information than what is provided. How do I create the metadata page, menu page, etc. We use Captivate 9, but are in the process of upgrading to Captivate 2017.
