Series Tag

Is there a way to incorporate the "series" tag, into a basic recipe?

i.e.:

class dailymirror(BasicNewsRecipe):
cover_url = 'http://www.johnsilva.ca/covers/dmirrorcov.jpg'
title = u'Daily Mirror'
author = 'News Articles'
description = u"News Articles from Daily Mirror website"
-> series = 'News Articles'
oldest_article = 7
max_articles_per_feed = 100
auto_cleanup = True

feeds = [(u'Breaking News', u'http://www.dailymirror.lk/index.php?option=com_ninjarsssyndicator&feed_id=16 &format=raw'), (u'Technology', u'http://www.dailymirror.lk/index.php?option=com_ninjarsssyndicator&feed_id=15 &format=raw'), (u'World News', u'http://dmadmin.dailymirror.lk/index.php?option=com_ninjarsssyndicator&feed_id=12 &format=raw')]
