Is there, is there planned, or could there be planned a view option so that items in a subcollection can be viewed when in the parent (sub)collection?

For example, I may add an item to Auditory>Physiology>Binaural. Later, searching for the same and related items, I may simply click on the physiology subcollection, type the author's name, and wish to view results including the item in the binaural subcollection, but limited to the physiology subcollection. Short of adding every item I add to their respective parent collections (which, in addition to being quite a hassle, also loses the ability to turn this feature off), it could be very helpful to have a toggle feature allowing viewable items (in particular search results) to include items in any subcollections of the current view.
