Nstart suggests some old and trusted users, but in the end it copies their following list, so we choose the initial limited selection but actually these people create the final lists. In the future I will probably add some sort of "starter packs", that will also include coated selections by countries or languages. To achieve what you want now, as suggested you can add one more npubs (separated by commas). You can also trick the system: create a fictional "French community" user and use it to follow a bunch of people, then add it to the suggestions!
