Change reply-to address for WooCommerce emails

Can anyone help me work out how to change the email address that WooCommerce emails come from? I mean the emails that a customer gets when they place an order. At the moment it's coming from the main email address in the WordPress settings. I don't want to change that as I want site notifications still to come to me but as this is a site I manage for a client I'd like shop emails to come from them so customers can reply more easily. Any ideas?
