The Panopticon/Comic Designers

From Tardis Wiki, the free Doctor Who reference

I noticed that the infobox for the comic stories doesn't have a section for comic Designers, which is one of the credits given to Rob Farmer for After Life. Farmer is credited twice: first as a Designer, second as a cover artist for the photo variant of the cover. I'm trying to figure out what to categorize the Designer credit under because I realized there's a distinction between illustrators and comic artists.
