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.
Check out this clip from Planning Center University.
To view service times and length of each item, click the menu in the top right corner, and make your selections in the Times section.
Remove an item from only one service by clicking in the appropriate time column. The times around it will automatically adjust based on the removed item.
To add the item back to that service time, hover over the empty space and click include.
You can create a separate report for each service time using Standard Reports.
