Non-Duty shift codes should show as 'Rostered Off' in the timesheet summary.

The timesheet summary on the home screen shows when a user has last entered their timesheets. When that user is on leave the summary does not flag red when timesheets have not been entered for some time. It also displays an (on leave) tag.

I would like a checkbox option to treat non-duty shift codes in the same way for operators where the crew are expected to be off for extended periods of time. This should be configurable per shift code.
