Updating project languages when updating a template in Studio

Hi all,

Is there a way to update the language combination of a project template (both for Studio 2014 and 2017) after you have created the project with your preferred languages?

I created a project template EN-FR but when I create new projects using that template, it includes several targets that I never added. I modify the languages to create a new project and update the template at the end, but whenever I use the template for a new project it includes again all the other target languages...

Any ideas, please?

Thanks,
