In Visual Studio .NET / 2003 is there a setting, or something I can do to keep the wysiwyg editor from rewriting / reformatting all of my hand coded html?

This is within a C# web application. I am using complex embedded tables for the layout etc. and by the time the wysiwyg editor is done with my code it is utterly illegible, and there are illogical line breaks in the code... in places ENTIRE tables were written on ONE line! ugh.
