CMS Is there a way to place ad inbetween articles?
 

For my CMS frontpage I'd like the following "setup".

featured
advert
X|X|X
X|X|X
X|X|X

Featured is a flagged article that
always comes on top. (replaced when a new featured is made)
X represents articles from all subcat's (3 columns (or 2 if needed))

Is this possible?
