How to update a customer record in Oracle TCA when the customers name changes?

We have several customer's that change their names.  Our policy has been to create a new record and link the new record to the older customer names.  We want to maintain record history with the customer's old name.  This causes my users to change every sales order to the new customer name.  There has to be a better way.

Any ideas to make this easier?

thanks
