How to override manual posts field?

I’m not trying to add custom field into CRP metabox, because implementing proper post selection from scratch is not that easy. So instead I’m relying on ACF to do that.
Right now I have ACF field with type “Relational -> Relationship” called related_posts. I enabled taxonomy filter and search for it. I set return format as “Post ID”.
Here is how it looks: https://i.ibb.co/xLvQqGg/image.png

There are 2 possible way of integrating this field with your plugin manual posts field.

1. On post save action take related_posts, retrieve crp_post_meta and add value of my custom field into your plugin meta. I decided to not go with this at the time, mostly because I didn’t want to do permanent changes just in case.

2. Override your plugin manual posts on frontend.
Your plugin doesn’t have a filter:
$manual_related = apply_filters('crp_manual_post_ids', wp_parse_id_list( $this->crp_post_meta['manual_related'] ));
So I had to override crp_post_meta when it’s retrieved.

if (!is_admin()) {
  add_filter('get_post_metadata', 'gp_child_crp_manual_posts', 100, 4);
  function gp_child_crp_manual_posts($metadata, $object_id, $meta_key, $single) {
    if (isset($meta_key) && 'crp_post_meta' === $meta_key) {
      $related_posts = get_field('related_posts', $object_id);
      if (!empty($related_posts)) {
        $crp_post_meta = gp_child_raw_crp_post_meta($object_id);
        if (!is_array($crp_post_meta)) {
          $crp_post_meta = array();
        }
        $crp_post_meta['manual_related'] = implode(',', $related_posts);
        return array($crp_post_meta);
      }
    }
    // Return original if the check does not pass
    return $metadata;
  }
  
  function gp_child_raw_crp_post_meta($object_id) {
    remove_filter('get_post_metadata', 'gp_child_crp_manual_posts', 100);
    $crp_post_meta = get_post_meta($object_id, 'crp_post_meta', TRUE);
    add_filter('get_post_metadata', 'gp_child_crp_manual_posts', 100, 4);
    return $crp_post_meta;
  }
}
