ps_emailalerts email template (editing the product lines)

[nick_developer]

Hi,
I'd like to edit the product lines in the order confirmation email sent by ps_emailalerts.
I have found the template file in /ps_emailalerts/mails/en/new_order.html but the product list is in the variable {items}

In the standard email template that row is being built by order_conf_product_list.tpl but I can't file the same file for the template used by ps_emailalerts.

Thanks for helping
