get_incoming_links() options

Hi, I tried using the following

$links = get_incoming_links();
$incoming_links_posts = CCTM::filter($links, 'get_post');

to get the links for the relation fields. Right now its pulling links from all the Custom Fields. Is there an option to get links from just one Custom Field?
