The current week of a schedule can easily be copied to all the other weeks via the Global Copy 
button on the Schedule Detail tool bar.
When selected, COMPASS will ask for confirmation before proceeding with the copy. Click Yes to copy the entire week (all elements) to all weeks of the schedule. This feature is useful if all schedule weeks are essentially the same, with some weeks varying as to number of ads per day, days active, etc. Once the global copy is complete, individual weeks can be adjusted as needed.
The global copy can be reversed by clicking Undo 
on the tool bar.
