I have next tree

Main (mainPage)
  News (news)
    Arch (newsFolder)

And I need next tree for news archive

Main (mainPage)
  News (news)
    Arch (newsFolder)
      Year (newsFolder)
        Month (newsFolder)
          News1 (newsItem)
          News2 (newsItem)
          News3 (newsItem)

I configure web.config like next

  </appSettings>
    <add key="itemDocType" value="newsItem" />
    <add key="itemDateProperty" value="date" />
    <add key="dateFolderDocType" value="newsFolder" />
  </appSettings>

And DateFolder creates folders under Main page like next

Main (mainPage)
  News (news)
    Arch (newsFolder)
  Year (newsFolder)
    Month (newsFolder)
      News1 (newsItem)
      News2 (newsItem)
      News3 (newsItem)

Where I wrong? May be I should create newsArch doc type for news archive?

Main (mainPage)

      Year (newsFolder)
        Month (newsFolder)
          News1 (newsItem)
