8 - Is It Possible To Create Routes Through The Admin
You may want to check out the Rabbit Hole module. 


  Rabbit Hole is a module that adds the ability to control what should
  happen when an entity is being viewed at its own page.
  
  Perhaps you have a content type that never should be displayed on its
  own page, like an image content type that's displayed in a carousel.
  Rabbit Hole can prevent this node from being accessible on its own
  page, through node/xxx.
