I would like to be able to create a Logical Collection in Collection Discovery that combines the results of at least two different logical sets.

CASE EXAMPLE: I have been asked to create "New Book" collections for multiple departments that include both print books and ebooks. For the print books, the fields I need to query on are only available the creation of a Physical Titles search set. For the ebooks, the fields I need to query on are only in an Electronic Titles search set. Since I cannot merge the results into a single logical set, that means I need to create two different "New Book" collections for each department.
