Adding Discussion or Survey Part to Document Library

Using MOSS 2007 we have setup a knowledge base site (based on the template downloaded from Microsoft)   The problem that I have is that I have no way for the user to provide feedback on whether or not my knowledge base article was useful.   To solve this I would like to add either the dicussion and/or survey webpart to each page to gather feed bac on how useful the posted information was.  

At one point I created the new survey and discussion board and I modfied a couple of the pages to include the new part but that just made the same discussion show up on the all the pages.  I am looking for the discussion and survey to be specific to the page I am looking at.   I am thinking I should be able to modify the default view to include a dicussion or survery and have the items display that are specific to that page.  How does one accomplish this without creating a  discussion or survey for every library article?
