Represents the numbering scheme based on an already existing production. The scheme allows you to re-use the Bates numbering fields from a previously-run production set. With existing production numbering you can change markup sets or header and footer designations without changing the Bates numbers. For example, you can use the scheme if a court order requires that your documents be produced without an already-applied confidential branding or if you need to redact already-produced documents for privilege.
