The Schedule page now features an option for Duplicate, allowing users to easily copy a shift that is already existing. 

From the schedule page, click on the shift that you would like to copy, and select Duplicate. In the example below, the Housekeeping shift is selected, and the Duplicate option is shown.

Click on Duplicate, and a new Housekeeping shift for the same position and time is created. This shift can then be drag-and-dropped to the appropriate Date and/or User.
