Editing 'VATSIM Approved' suggested routes

As Simbrief recently included the ability to prioritise ‘VATSIM ATC Approved’ Routes, I have two questions to ask regarding this feature.

  1. Is anyone able to change the routes as these may have been cleared by a trainee and is not accurate or valid.

  2. How does the system determine that the route was approved by VATSIM ATC? What is the confirmation factor?
