I am not sure how things work at other universities, but here, its most common for the same professors to teach the same courses for several years in a row. As such, I tend to create lists for these professors using standardized names with a format that's similar to the course numbering system here. For example, a professor Smith who teaches CIS10 would get a list called CIS10-SMITH. This list would then be retained for several years. The lists I need to retire tend to be for organizations and departments that no longer exist.
