Course Catalogue Under Construction Status

In the course catalogue, would it be possible to add a status of "Under Construction" or something similar, for courses we are in the midst of building, but are not ready to publish yet? Right now the only options are "Active" or "Retired". I would like to be able to have a course that I am preparing but is not yet published. Marking it as "Active" but "Unpublished" does not quite work for us. Thank you for considering this
