[Koha] marking orders as cancelled

Hello, Is there a way in Koha to mark an order as cancelled? This way the order would still be in the system, but it would not show up as an outstanding order with committed funds. I've only used Sirsi, so I don't know if this is handled differently in other systems. What do others do if you end up cancelling an order? Thanks.
