Help Required

I was hoping that someone from SI could help me. I am trying to compile a background pack for the media sources in-game (such as BBC Sport, etc). These all have unique id's within the editor, however I cannot fathom out the directory for these when creating my config for them. I have tried all, person/comps, etc but to no avail. If there is anyone who could point me in the right direction, or if this is even possible at all, I would be grateful.

Thanks :-)
