masonry custom post type and custom title / avf_masonry_loop_prepare

Hi, I have successfully been able to use masonry in avia layout editor with custom post type. But I would like to customize title display, and I use the function below. Is there another method than looping all entries at each entry display to modify the title ? code below , thanks.

 
add_filter('avf_masonry_loop_prepare','breizhwave_memberTitle', 10, 2);
function breizhwave_memberTitle($loop, $entries)
{
     foreach($entries->posts as $key => $entry) 
	 {
	$id=$entry->ID;
	 if ($id=$loop["ID"])
     {
		 
        if($entry->post_type == "membre")
        	{
 		 	$ville=get_post_meta($id,"ville",true);
            $loop['the_title'] = "<b>".  get_the_title($id) . "</b>" .  " "  .$ville;
       		}
	 	}
  	}
 
    return $loop;
}
