Is it possible to sort iTunes U other than "Released Date"? In iTunes > Library > iTunes U, the items are sorted by Released Date. How can I sort the items, say, by Name?
Sorting by "Release Date" is currently the only option for sorting iTunes U in iTunes. 

The sorting of content is meant to be left up to the creator of the iTunes U collection/course.

The collections are automatically sorted alphabetically by collection name. If you click on the disclosure triangle for each collection, the lectures can then be sorted by release date in ascending or descending order.
