I'm not sure if there is a better way, but you could mark all the clubbers as excused for the last week (From the Check-in List's pop-up menu, choose Excuse > Excuse the club and SS absences for All members for this week), run the Attendance Awards tool, then un-excuse all of your clubbers.
Again, there may be a better way, but I filter the Clubber list to quickly see perfect attendance. Make sure the "Attendance and Dues" header band and "Attend" column header are visible. Then click on the little triangle in the "Attend" column header & select "27/27" for example, if you have 27 weeks in your club year. If you need a printout, you can click the Printer button in the toolbar.
