Breadcrumb addition possible?

[kether1]

In my breadcrumb when I am at the forum thread level I see three links like this:

vbAdvanced (index.php)>>>category Page>>>>forum page and the thread title (which is not a link.)

My question: Is there a way to add a link to the main forum page that list all of my categories(the real forums page)? It would have 4 links and look like this:

vbAdvanced (index.php)>>>forum.php page(category lists)>>>category page>>>>forum page

I hope I am explaining this correctly. I found the 'breadcrumb after last post mod', but it is the same as my main breadcrumb. Thanks for your help!

Kether
