Validating Protected Pages

This is a feature request...
 
We develop courses which require users to login for access and tracking
purposes.  The pages are not static.
 
The only way I can validate these pages today is to login, navigate to the
page, VIEW SOURCE, SELECT ALL, COPY.  At this point, I have a copy of the
HTML in the copy/paste buffer.
 
WDG offers a direct source input option at
 
http://www.htmlhelp.com/tools/validator/direct.html
 
I then load the URL above, SELECT ALL, in the text input box, PASTE, then
press VALIDATE.  
 
I'd like to see this whole process be a single icon click resulting in a W3C
HTML and / or CSS validation.
 
Thanks,
 
Sam
