[TxMt] [Blogging bundle] Request specific post by ID

[Steven Harms]

I love the blogging bundle, and the primary 'fetch' use case would be  
to fetch within the last n-many posts, in the Blogging bundle, the  
value of n is a nice and sensible 20.

BUT

What if I decided that I wanted to go back and edit something from a  
*long time* ago.  Could I somehow retrieve the post via the bundle  
either by slug or by unique ID?
