Duplicate (copy) multiple courses at once?

Hello everyone,

is there an option to duplicate / copy multiple courses to another category at once? Or to duplicate a category that consists of courses?

We have school year as a category and need to duplicate courses for every new school year. I know that there is a copy option for each course, but we have 70 courses so it would be time-consuming to copy each course at a time, every new school year.
