Class Descriptions - using templates

At times we need to change a class description but in order to do so, we have to open up each individual class. I realize I can copy & paste, but it would be nice if those were in an area that can be seen & edited all at once. Perhaps have a seperate area to create a template (like the email templates) and then select which 'template' to use when you add a class. Once that populates, if I need to edit anything on the fly I could but it wouldn't change the template.
