Each team in an org should be able to make their own picklist. If an org has multiple teams, show a dropdown on Alliance Selection Data and Alliance Selection to edit and show their own team's picklist, respectively.
NOTE: to avoid people accidentally viewing and editing the wrong picklist, I think they should be forced to pick their team from the dropdown BEFORE the data appear.
