You can easily specify the minimum number of days the auto scheduler will leave between services for each volunteer. To set this number:
1) Open any schedule or skeleton inside of MSP.
2) From the open schedule, click on the Schedule menu at the top of the window and select “Scheduler Settings.”
3) In this window, check the option that says, “Always leave at least ‘2’ days between the services of each volunteer,” and change the number ‘2’ to the desired number of days.
