I often need to make updates to many courses at the same time. I have template versions of the course that then get copied out to the instructors. Sometimes, I need to make a change to one page or one module. There are warnings that importing the same content with the same name will overwrite existing content, but that hasn't happened very consistently when I use the course import or "copy to" functions. It often ends up creating duplicate versions instead, so I end up just going into each instructor's course and making the updates by hand. Is there an easier way to do this or to intentionally trigger that overwriting process?
