Updating Safari Bookmarks To Show Page Title Instead of Page File Name

I have hundreds of bookmarks saved in Safari. Many of them are easily recognized when I browse through them with bookmark titles like:

Code:

Bare Bones Software | Textwrangler 
The Principles of Good Programming

Those are based on the Safari browser title.

However, I have many that are titled just based on the page name like:

Code:

index.htm
favorite.html
index.php?id=119

When I go to these pages, though, they have readable browser titles like in the first set of examples I posted.

Is there an automated way to go through all Safari bookmarks and replace all the titles, no matter what they are, with their respective browser page title names?

It would seem awfully inefficient going through even 100 of the page name only based bookmarks individually, loading up the page, and retitling the bookmark manually.

I imagine there might be a programmatic way to do this (automator?); but something already available would save a bit of time.

Thanks.
