Application Development Software

We are building a website. Here is the problem. We have several news releases contributed / checked in as word documents.
We will create a primary layout to display the news releases by date, we will use dynamic list query to display the news release search results.

When user clicks the news link from the search result, we want to display the news content (word document) as a HTML using Dynamic converter.

The problem is we have so many news releases (word documents), do we need to create layout page for each word documents.
How I can use single layout page, and display different word documents based on some type of input or query parameter etc… what is the best way

Thank you
