is it possible to change the uiculation used for orcwizard?

So, after checking the examples I found out that you have to use the catel language service. I added this in App.xaml.cs

protected override void OnStartup(StartupEventArgs e) {
    var serviceLocator = ServiceLocator.Default;
    var langService = serviceLocator.ResolveType<ILanguageService>();
    langService.PreferredCulture = new CultureInfo("en-US");
    langService.FallbackCulture = new CultureInfo("en-US");
} 

This did the trick.
