TC.K on "[Plugin: WooCommerce - excelling eCommerce] Paypal Standard gateway,changed status to pending when cancelled."

I am using a paypal standard gateway.
When the customer cancelled the payment in the paypal page, the order status will become 'Cancelled'.
How do I change the status to 'Pending' when customer cancel the payment in paypal page??

Thnaks.
