Dynamic Slide/Menu Names

I'm creating a course that will be viewed by both American and Canadian users. Along with that comes localized spelling. In order to ensure consistency across versions, I am using the same story file for both and including a location variable that's set when the first slide Timeline starts. I'm not having any issues getting the slide content to adapt to the localization. But, some of the slides have names that should reflect this localized spelling too. Is there a way for the Menu to display the correct slide name?

I presume it will be a JavaScript solution that I trigger immediately after assigning the variable, but I'm not sure how to build it out from there.
