Possible to hook ads to the end of post?

Hi team,

I love the way this functions, with custom post types powering ads, ability to hook into categories and all sorts of great stuff and lots of flexibility.

BUT!

I'd like to be able to hook this into the end of the post, rather than after x paragraphs or any other in-post modifier. Is there something I can add to functions.php or similar which will call the in post ad there, bypassing the "after x pararaphs" command?

Thanks,
Craig
