In short, Borateen, yes, creating a batch is something of a pain. Most groups prefer to minimize the number of batch torrents they create for a series. And to be frank, episode 34 of a 45 episode series is not a logical breakpoint for a batch. Keep in mind that most clients will allow you to choose which files of a torrent you download, so it isn't difficult to only get the episodes you want from what is available.
