Override helper.php on mod_related_item

Question

I want to get the related items of an article order by created and only show the related items that have the same catid.

To accomplish that i must change the helper.php code and add this code:

$catid = JRequest::getInt('catid'); 
if($catid){
    $query->where('a.catid='.(int)$catid);
}
$query->order('a.created DESC');

The problem here is, i don't know how to override the helper.php on my template. I've already tried to create the file templates/<template>/html/mod_related_items/helper.php and copy the core code to there but it didn't work.

How can i accomplish this without editing core code?

Templates can only override template/layout files. You can fork the module or use a plugin like MVC Override https://gruz.ml/en/extensions/mvcoverride.html.
