More than 5 query IDs in the search core results web part?

I need to have six search results web parts on the same page, all using the FASTSearch location, but each with a separate Search Action Links web part to sort  it.  But there are only 5 cross-web part query IDs available.  Is it possible to extend the Search Core Results web part to have more than 5 queryIDs?
