Search by Open Cases/Case Management

Could there be an option to search by open cases? As a way of checking on those patients who we may have seen a while ago but whose treatment was/is ongoing (or patients who have not booked back in and are wanting to self manage their ongoing rehab) so that we can remember to follow up with them? I think that could be a really helpful addition at some stage so that it enables us to follow up with those “forgotten” patients.
