Jane,
You pose an excellent question, particularly for teachers who would do repetitive classes or many classes. I think that WizIQ did not fully appreciate the ramifications of such a teacher. They are now beginning to accomodate the prolific teacher. The most recent evidence is the soon-to-be-released class scheduling function which will allow for repeating classes.
Their DB setup, I think is the prime culprit in this particular request. I would be surprised if they do not have it on their "to do" list. But, you should not hope for a quick fix. I have developed several work-arounds for my own sanity but they are labor intensive. I would be happy to meet with you to look at your anticipated class materials to offer some ideas.
Good luck
George
