Click on the schedules link above, and then click on 'balanced' for 8 items. Match 1 could be assigned to be the first sport, while the other Matches are assigned to the second sport. Playing the seven rounds would give all teams 1 or 2 games at the first sport and 5 or 6 games at the second sport. If you have a lot of time available, then it is possible to play 28 rounds where there is one complete round robin at the first sport and three complete round robins at the second sport (essentially this is four copies of the 7 round schedule rotating the columns one position each time). Hope that helps.
