Moving XML comments to a separate file

[BSmelody]

I love XML comments. However, with everything collapsed, every two lines looks like:\[code\][/// summary ...]public void CreateUser(string username, string password)[...]\[/code\]Multiply this by tens or hundreds of methods, and the resulting collapsed code is hard to sift through. Can I move these comments to a separate XML file, and still have Visual Studio recognize the association so that they still show up in the Intellisense? If so, how do I make that association? And I'm also using SandCastle to generate documentation based on these comments, so the association will have to be recognized by SandCastle as well.
