If you have two services, and one service has a special element like baptisms or a baby dedication, you can assign that item to just one service time, and it will not contribute to both service times.
View the times to ensure service stays on schedule by selecting the arrow.
If you have two Service Times, choose which items will occur in which service by clicking/tapping the time in the appropriate column to select or deselect it.
The times around it will automatically adjust based on the removed item.
Hover over the empty space and tap/click to add the item back to that service time.
