You can assign teams to specific home venues in the PRO version via the Manage Venues dialog (on the Schedule Maker tab).
Simply click the home icon next to the venue and select the team from the dropdown. Click the check mark to save.
If a team has home venues assigned, all its home games will be scheduled at those venues.
Exclusive home venue
Means no other teams but the assigned home teams can have home games here. If it's not checked, teams without home venues may be scheduled here.
