Scheduling conflicts

We have a number of people who carry multiple roles in various ministry areas. Is there a way to prevent scheduling conflicts when a person has multiple possible roles in a service?

Examples:
- If someone is scheduled to preach they cannot then be assigned to lead worship.
- If a person is assigned to kids ministry on a sunday, they can't also be assigned to play on the worship team.

This is another key feature that PCO has which I can't find in WorshipTools.
