I don't think so, you will have to do with head tags. <link rel="shortcut icon" href="mysite.com/favicon.ico"> <link rel="icon" href="mysite.com/favicon.ico"
For future reference use php to include the header information (including the favicon) that stays consistent on each page so that you only have to edit one file instead of a large number.
for now you can use a php script that will open each html file and for each one it can add the favicon. Pretty simple. better yet you can upgrade the website to use a cms. Thanks - Khaled
Or you could use something even easier like Search and Replace. You can basically search for a string of characters, and replace them with whatever you want. I use it all of the time to edit about 5000 html files.
