Template Parser question

[eluser]NateL[/eluser]
Is it possible to pull something specific out of the database, based on a given ID?

For instance, in the user guide example, you can do

Code:

{blog_entries}
<h5>{title}</h5>
<p>{body}</p>
{/blog_entries}

Can you do something like this?

Code:

{blog_entries=5}
<h5>{title}</h5>
<p>{body}</p>
{/blog_entries}

where "5" is the category ID.

Thanks
