Right-click on a reservation and select the Exceptions menu item. The option is inactive if the reservation does not contain any items with members that can be excluded.

Select the type to make an exception for.

All members and exceptions are displayed, regardless of membership type. Select a member type to display only members and exceptions of that type.

Add and remove exceptions as desired. Click the save button to save, close the dialog and update the calendar.

Reservations with exceptions are marked with an asterisk at the top left. The asterisk is white on dark bookings and black on light ones.

When a non-exempt member object is selected in the Selected List, the reservation is shown as normal.

But if an exempt member is selected, the Reservation disappears and does not constitute an obstacle.

All membership exceptions are shown in the Reservation Information panel when selecting a reservation
