View items in "My Library" that have not been assigned to any "collection" or "sub-collection"

I like to assign all items in "My Library" to one or more "collections" or "sub-collections". Usually I would do that while I create a new item. But sometimes, I forget. I want to be able to view all items in "My Library" that are not in any "collection" or "sub-collection". Currently, to identify such items in "My Library" that have not been assigned to any "collection" or "sub-collection", I have to manually click on each item in "My Library", then press and hold "Ctrl" key. This is a cumbersome task.
