Hi,

It’s a really old post but a solution with ACF 4 and a page link field is to create a new field type in a plugin or in functions.php of the theme. I suppose it can be done with a post field too. Here’s an example :

class acf_field_page_link_multisite extends acf_field_page_link
{

  function __construct()
  {
    // vars
    $this->name = 'post_object_multisite';
    $this->label = __("Page Link Multisite",'acf');
    $this->category = __("Relational",'acf');
    $this->defaults = array(
                       'post_type' => array('all'),
                       'multiple' => 0,
                       'allow_null' => 0,
		      );

    // do not delete!
    acf_field::__construct();
  }

	function create_field( $field )
	{
          // Switch to the blog you want
	  switch_to_blog(5);
	  parent::create_field($field);
	  restore_current_blog();
	}

	function create_options( $field )
	{
	  switch_to_blog(5);
	  parent::create_options($field);
          restore_current_blog();
	}

	function format_value_for_api( $value, $post_id, $field )
	{
		switch_to_blog(5);
		$value = parent::format_value_for_api($value, $post_id, $field);
		restore_current_blog();
		return $value;
	}

}

new acf_field_page_link_multisite();
