There is not a way to do it through the UI like there used to be in the map of X-Plane 10. If you know of inaccuracies in X-Plane's data versus the real world, please file a NAVAID bug report here so we can get it fixed for a later update.
If you want to add custom NAVAIDs, please read through the nav data spec for the guidelines.
