Improve customer order domain model

As a developer I would like customer order domain model to include export information and additional information about the order.
For better integration I would like to be able to seamlessly populate the model via shopping cart command interface

The following fields would be good to have:
TCUSTOMERORDERDELIVERY
EXPORT_BLOCK bit not null default 0;
EXPORT_LAST_DATE datetime;
EXPORT_LAST_STATUS varchar(255);
EXPORT_LAST_DELIVERYSTATUS varchar(64);

TCUSTOMERORDER
EXPORT_BLOCK bit not null default 0;
EXPORT_LAST_DATE datetime;
EXPORT_LAST_STATUS varchar(255);
EXPORT_LAST_ORDERSTATUS varchar(64);

B2B_REF varchar(64);
B2B_EMPLOYEEID varchar(64);
B2B_CHARGEID varchar(64);
B2B_APPROVE_REQUIRE bit not null default 0;
B2B_APPROVEDBY varchar(64);
B2B_APPROVED_DATE datetime;
