You can easily change the arrangement of your teams on the Teams page to an order that works for you.
The positions in your teams cannot be reordered because they are listed alphabetically.
To access the Teams page, click the gear next to Teams on a plan sidebar.
If you are in scheduling view with the People sidebar showing, the gear is next to Teams above the list of scheduled people.
Drag the handles to the left of a team to move it to a different position in the list.
