Updating Multi-language course in Storyline 360

Hello! Hoping to find a creative solution for updating a multi-language course that we have, built in storyline 360. Currently, the course package contains two branches (e.g. one branch takes learner to the English content and the one takes learner to the French content). Learner selects their language of preference on the first slide. Every year, we update the English content (regulatory updates) using the course storyboard, then we provide the updated text in word format to our translators, then we update the French slides manually. Because the course contains both English and French, I'm not sure how to go about automating the French updates so that it's not so much of a manual effort.  Wondering if anyone has ideas on how we could do this more efficiently?
