P: Filter selected images in proofing collection

It would be great if customers could filter only to show selected images in their proofing collection. 

I am referring to when you sync a collection with lightroom and then on lightroom.adobe.com you share the proofing link. As it stands right now a person with the link to the proofing collection can make selections in the collection but is limited to a gallery view with all images and can not filter to only show selected images so they can fine-tune the selections.
