Any existing schedule can be copied to the same client or to a different client. From the main window, highlight the schedule to be copied, then click the Copy button 
on the tool bar or from the main menu select Schedule > Copy.
The selected schedule will be opened in the Schedule Information window with the title in the upper right corner changed to Copy Schedule. At this point, any portion of the schedule can be edited, including changing the client. If you are copying to the same client, make any changes in the ads/weeks desired and be certain to change the schedule description. Each description must be unique for the same client.
If you are copying the schedule to a different client, select or create the client, make any other changes necessary, and save the schedule as normal.
