Import dir of files from Ember Addon

I'd like my addon to import any file the host app may have added to a certain folder, say /app/pretender/routes. Is this possible?

I can get the listing of files from my addon's /config/environment (since it's a node file), and add the listing to my addon's ENV, but I wasn't able to do anything like

ENV['my-addon']['routes'].forEach(function(route) {
  import x from route;
});

Is something like this possible?
