Family members will automatically not be scheduled for different services on the same weekend. If they are being scheduled for different times on the same weekend, first make sure that the family groupings are set up correct by looking at them closely in the Family Groupings pane. Then:
- Choose "Scheduler Settings..." from the Scheduler menu of any open schedule or schedule skeleton window
- Make sure the "Don't schedule family members for different services on the same weekend" option is turned on.
The next time you run a schedule a couple should never be split up for two different services within 48 hours of each other.
