The ISN has a great feature that allows a user to block off time on their calendar that is not related to an inspection order. To block off time for a specific date, navigate to Calendar -- Add Event.
From there, select the owner of the calendar, the inspector or user calendar the Event will affect, by clicking on the arrow of the drop down box. Follow the prompts to select the date of the event, time frame of the event, title, and description of the event. This Add Event feature also allows you to let the system know if this will be a recurring event or not.
Once the event is on the calendar, the pencil button allows you to edit your event if anything changes or deletes the entire event.
The Events you have added to your calendar will also be applied to your Online Scheduler calendar in order to avoid an inspection being scheduled when the inspector is not available. The inspectors nightly email will also provide information on any calendar events they have scheduled for the next day.
