Let's say I created example.com/profile/facebook, and then I also created example.com/profile/twitter. Once the 2nd link is created, a "Profile" Tag should automatically be added to BOTH of these links — and also for any links created in the future that contain "/profile".
You could also add an option to disable this "Automatic Tagging" in settings if people decide they don’t like it. Personally I think it would be good for organisation.
