I have a customer that has a GL Chart of Accounts that only has 1 segment. They want to add three more segments to the accounts. I know  that I can add those three new segments to the right of the existing segment (using PSTL add the values to the existing accounts), but they want to add one of those three segments on the left of the current segment. For Example: they have now:

99999 and they want 000-99999-000-00


they already have transactions and they don't want to lose them.


What can I do to solve this?
