go to deploy a bundle. In the deploy wizard, there is a green + button that lets you create groups. Click and and go through the create-group wizard - assign it a platform. Now when you go back to the deploy wizard, the group still doesn't show in the drop down. Go to the main Inventory>Groups view and notice there are no members in the group. For some reason, assigning group members to the group from the bundle wizard didn't work.
