fandom sub categories for zines (or really all fanworks)

[ratcreature]

Yesterday and today I have started to add zines pages that have been added as articles to lists on the respective fandom (sub)pages so that the zine articles wouldn't be orphaned and could also be found more easily (the search rather sucks). However this is drudgery, as I more or less just do data sorting and reassembly by hand. It would make much more sense, IMO, if the zine category had fandom subcategories, and when creating a new page for a sentinel zine it would just have a category "category:zine:sentinel" or something like that. Then if for easier display one would still like a list on the fandom zine subpage one could at least c&p the list the wiki assembles instead of going through orphaned pages and/or search results by hand. Why aren't there fandom subcategories?
