loadfile for dynamic routes

[Ali-Hussein-dev]

I need to use the namespace "projects" for routes that like for /protected/number/ or /protected/33947329874/ how can I achieve that?

{
  "locales": ["en-US", "de"],
  "defaultLocale": "de",
  "pages": {
    "*": ["common"],
    "/protected/projects": ["projects"],
    "rgx:/protected/[0-9]+/": ["projects"]  // <------ file is not loaded
  }
}
