[1.6] How do I add a column to the stock movement page?

[5haun]

I would like to add a 'supplier name' column the stock movement page. How do I achieve this?

I actually managed to successfully do something similar on the product page by creating an override. Here's the code for that if it helps at all:

class AdminProductsController extends AdminProductsControllerCore
{
    public function __construct()
    {
        parent::__construct();
        
        $this->_join .= ' LEFT JOIN `'._DB_PREFIX_.'manufacturer` m ON (m.`id_manufacturer` = a.`id_manufacturer`)
				LEFT JOIN `'._DB_PREFIX_.'supplier` AS supp ON (supp.id_supplier = a.`id_supplier`)
				LEFT JOIN `'._DB_PREFIX_.'product_supplier` ps ON ( a.id_product = ps.id_product AND ps.id_product_attribute = 0 )';

        $this->fields_list['manufacturer_name'] = array(
            'title' => $this->l('Manufacturer'),
            'filter_key' => 'm!name',
            'orderby' => true,
        );
        $this->fields_list['supp'] = array(
            'title' => $this->l('Supplier'),
            'filter_key' => 'supp!name'
        );
		$this->fields_list['product_supplier_reference'] = array(
			'title' => $this->l('Supplier Reference'),
			'align' => 'left',
			'filter_key' => 'ps!product_supplier_reference'
		);
    }
}
