Redirect to first child a few folders deep and only a certain template using wayfinder?

I have a blog which has a structure like:



I use wayfinder to generate my menus and the "blog home" link is wayfinder generated. I use wayfinder as it applys the "active" tag to all pages that are parents of the current page no matter how deep you are - it's great for styling.

Can I use the wayfinder (I could put it in another call and use &includeDocs as the menu won't change often if ever) to make it so that when I click on "Blog Home" I can jump to the latest blog post? I've had a look at FirstChildRedirect but it won't go deeper than the first child....

Thanks in advance!
