Hey Glenn, thanks for writing in! Currently, in order to add teams to a scheduling group you have to select a program and division from the drop downs. This will then list all teams that have been created for this division. You can then add teams by clicking on one then click on the "
>" button. You can add multiple teams by holding down control on your keyboard, and then clicking on the ones you want to add. You can also hold down shift on your keyboard and it will allow you to select an entire listing.

I will submit an enhancement request for you that will allow you to add all teams to a group without having to select what program and division they are associated with.
