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.

THIS!! Please add this feature to Planning!

We really need this feature. Different people schedule for different departments and need to be aware if someone has already been scheduled. Sometimes it's okay to have double ups, for example welcome before the service and coffee afterwards, but sometimes it's not okay and the scheduler needs to be aware without constantly searching.
