Batch (or bulk) sharing

I would like the option to batch share and reshare from public to unlisted (and vice versa). As a teacher, it would help to streamline my workflow if I were able to refer to a list of all unlisted and public pages I have at a glance - much like having a list of Rems using tags. Then, from this list, I could quickly update the status of each Rem between unlisted and public. A lot of times, I am in and out of documents, making changes, so it would be great if I had the option to reshare all unlisted and public documents in one step (or click). This would allow me to keep shared Rems up to date in terms of who can see what.
