admin button posting to specific cat

$menu[5] = array(__(‘Add Dates’), ‘edit_posts’, ‘post.php?cat=2’);

I’m trying to add an option to edit a specific category through the admin menu. I’d like to be able to say add news, and just add posts to the news category with his cat=1 but is the default, so thats easy… How would I do the same thing with adding a button that will point to cat=2? to add event dates?
