It is possible to create a Non-Job related Appointment which will block a Resource's time and appear differently to Job Related Appointments.  This feature is useful when a Resource takes holidays or requires time away from work for meetings/appointments.  The Non-Job related Appointment will be displayed with the Non-Job coloring default of red diagonal lines or as otherwise setup in the Appointment Coloring Tab of the Options application.

Step 1. Add an Appointment selecting the Resource required and uncheck the Job Related checkbox within the Job Details Tab of the Add Appointment Window.

Step 2. Under the Time Entry tab specify the start and end dates and times that the Resource will be unavailable.

Step 3. Under the Notations Tab insert a notation to provide details of the Non-Job related entry.  This notation then becomes the Appointment label displayed in Views.
