Inserting home center courses into sub learn centers

Summary

Is there a way to Bulk Load existing course in sub learn centers?

Content

Is there an easy way to load courses that are in our home center to sub learn centers without having the "Insert Existing Course" every course? We have about 250 courses we just added from OpenSesame, but the only way it seem that I can add them to the sub learn centers is by adding each individual course using "Insert Existing Course". I've tried using the bulk loader "Course Manager", however, when I upload the courses using this it removes the course from the home center....Any ideas?
