WebPT Ideas and Discovery

When reviewing sessions it would be very helpful to be able to filter by date. We only recently started reviewing all sessions. Since i can only search by therapist, some therapist have a few years of unreviewed claims in the queue. Not sure how to get rid of those. Searching by date would solve it. Also...what is the check box for on the review documents screen? I can check the box next to each session, but their are no options to choose from for the group selected.
