Using defaults for stylesheet link tag

Hi. i was wondering if someone could tell me how to pass more than one
stylesheet to the stylesheet_link_tag? I can do something like <%=
stylesheet_link_tag ‘item1’, item2’ %> and it works great. I would like
to do <%= stylesheet_link__tag :defaults %> and have defaults be
‘item1’, item2. This is similar to the way the javascript_include_tag
works. Can someone help? Thanks very much!
