You can assign staff positions in the admin panel without hours and flights stats. This is easily done by assigning a New Role, go to Pilots & Groups, then click on Pilot Groups, up in the very top hand left corner you will see "Add Group". Assign the Role you wish to have. After doing so, you can then go back and assign that role/s to the said Pilots. This has NO baring on any Flight Hours or Flights.
On another note, also vStaff is outstanding for this to, runs on its own, and each role can be setup as you wish, below is a link on my site for you to view with vStaff if you'd like.
