A: If you are fielding an "A" team and a "B" team, include the "A" team as you normally would (either click Include to pull in the pre-defined roster or click New to define the team roster from scratch). Then click New to add the "B" team -- when prompted use the same team ID as the "A" team followed by a # sign (and any other characters as desired). For example, you could use WAB or WAB#B.
