Good Morning Nikki, As David and Skye mentioned, you add statuses that can then be used as columns on your board by making them System Statuses. I've got different 3 different boards with different columns, plus we run "normal" statuses for the rest of the company without any confusion. Its a bit of hack, but here's how you can do it.
For Agile Teams, the statuses need to be System Statuses that are Locked in order to create or modify the story board - not just for the specific team.
AFTER HOURS: Create the System Statuses in Locked state
Create Projects and/or Teams to use.
Modify Project Agile View, and Scrum or Kanban storyboard to include the new statuses.
Unlock associated System Statuses
Hide associated Statuses from other groups besides the group you need it for.

Let me know if you have any questions. John Albaugh
