Customer Renumber using Delete/Change Utility does not renumber customer in SO_SalesOrderHistoryHeader

Why doesn't the SO_SalesOrderHistoryHeader file get updated with the new customer number from the Customer Delete/Change utility?  I've renumbered and merged several customer numbers and this is the one file that does not get updated.  This file also is excluded from the extensive list of data files that do get updated, per the Sage KB article number 18208.  Is this by design, or just a forgotten about file to update?  

Change Tab - The following files are updated if you change a customer number.
