See unsorted books in "Books"

In the previous "iBooks" app there was an "All Books" collection and a "Books" collection.

The "All Books" collection shows all books even if they are sorted into our own collections but the "Books" collection showed only books that hadn't yet been sorted into other collections. That is great for knowing which books still need to be sorted. To have to scan my whole library and guess which books have been sorted or not is not fun.

Is there a way to see unsorted books with "Books" in the newer iOSs?
