The Panopticon/Big Finish extras

From Tardis Wiki, the free Doctor Who reference

I have recently started to look into some of my most anticipated Big Finish audios, and I have not been disappointed, by neither the stories or the bonus material. However, I have noted that these bonus stories, sometimes twenty to frothy minutes in length and fascinating, have no current page basis on this site. I've checked out a few of the discs that I have as well as the sleeves, and I have noted no names or labels other than "Bonus." Should we make pages for these extras? And how do we tell them apart? And what would we call the pages?
