Add a ref type for "tv progamme" and/or "streamed video"
We would like more reference type options to support users adding content from streaming platforms such as BBC iplayer and the BUFVC site Box of Broadcasts. Currently we only have the basic 'video' option which is fine for adding films which require details such as director, distribution company etc. but the information needed to reference a tv broadcast in our Cite Them RIght Harvard style is quite different. An additional reference type would allow us to configure this to accomodate both types of video content.
