The Panopticon/Distinguishing between info from TV/books/audio

I was on Tower of the Hand; the wiki for Song of Ice and Fire, and they have a bit of code that allows reader to determine how far into the series the article shows. Would it be possible to set up the same for the Tardis wiki, but rather then make a distinction between books, make it between mediums?

For example, the first sentence in the article on The Great Intelligence is from a Virgin new adventure that connects that entity to HP Lovecrafts Great Old Ones. I think thats an interesting idea, and the fact that a Who writer has drawn that connection should be on this wiki. But that hasn't been established on the show, and future writers of the show will not think twice about contradicting that info. A TV viewer coming to this site for info on whats been established in the show would be nothing but confused by that.

The work of citing the various sources for info has already been done, this would just make it easier to sort through.
