Reply To: Multi level numbered list across documents

I meant Indesign’s automatic chapter number. You set the first chapter number in the ‘Numbering & Section options’ of the first chapter. The rest of the chpaters you set to ‘Automatic Chapter Numbering’. Then in the paragraph styles you use the ‘Chapter Number’ placeholder as the first number of the automatic section numbers. The only manual process is setting thing up, from then all everything is automatic.
