If you would like MSP to automatically label scheduled positions in this ministry then check the box that reads "Automatically number or label positions in schedules". This feature is useful if you have, for instance, four different Usher positions and would like to indicate which volunteer is assigned to which position using a predefined numbering or labeling system.
Once this option is selected, a new window will open and you can select whether to automatically number positions sequentially, or define a custom label for each position.
