Extras are generally listed as "Specials" by the various metadata providers (TVMaze, TVDB, etc). So to get the extras to show up, you'd need to put them in "Specials" - so you'd have the Season_xx folder(s) then a Specials folder. As for what episode # a given extra would be, check the listing for the show in the metadata provider.
