Select which relation(s) to display


I am wondering if it would be possible to customize the annotation interface for relations so that annotators can select which relation(s) to display on the interface?
Specifically speaking, in this example [link], it would be great if annotators could choose to display only COREF relations and hide already annotated POSS or OBJECT relations, e.g., add additional checkboxes for each relation, like COREF, POSS, and OBJECT, instead of All labels.

Thank you in advance for your support.
