Hi,
At this point is not posible, I would need to extend the admin, etc but it is a nice feature, perhaps in future releases.
Anyway if you want to create a template or use static html in your post editor I write the html structure, fill it, paste it in your home page and you′ll get 3 static extra boxes.
If you are displaying your last post (not static page) in frontpage this solution is not useful.
<div class="home-boxes row-fluid">
<div class="span4 box box-left">
<div class="thumbnail box-banner">
<a href="">
<img src="" alt="" />
</a>
<h3 class="entry-title"><a href="">Title</a></h3>
</div>
<div class="caption">
<p>Text description</p>
</div>
</div>
<div class="span4 box box-center">
<div class="thumbnail box-banner">
<a href="">
<img src="" alt="" />
</a>
<h3 class="entry-title"><a href="">Title</a></h3>
</div>
<div class="caption">
<p>Text description</p>
</div>
</div>
<div class="span4 box box-right">
<div class="thumbnail box-banner">
<a href="">
<img src="" alt="" />
</a>
<h3 class="entry-title"><a href="">Title</a></h3>
</div>
<div class="caption">
<p>Text description</p>
</div>
</div>
</div>
Best Regards
