The way the removal tool is currently configured, I don't think you can do what you want. However, you can block those urls in robots.txt. While it takes a bit longer than a removal request, those urls will drop out of the index, all except those that have backlinks may hang around in the search results as "url-only".
This the first usefull reply in this thread Ok first i want to know that if i block them through robots will google remove those urls which have no back links from its search and how long will it take and if i have dynamic link let say one is www.example.com/category/abc=1xy and i blocked above link while i add the other link www.example.com/category/abc if the first link is blocked by robots will google consider it as duplicate ?
You can remove links via Google WM Tools. Check back w/n a week. Great way to remove any duplicate content you may have on your site.
i think from google webmaster tool you can remove. you can use like this: <META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW"> User-agent: * Disallow: /~joe/junk.html Disallow: /~joe/foo.html Disallow: /~joe/bar.html
