Affiliate for WooCommerce

We are using a custom post type named MotoPress Hotel Booking plugin. It lists accommodation as custom posts so the affiliate direct link to an accommodation doesnt show the metabox in the edit screen.
The slug of the accommodation types is mphb_room_type you can refer to the lite version of the hotel booking plugin which can be downloaded and installed for testing purposes fo free https://wordpress.org/plugins/motopress-hotel-booking-lite/
