Hi EMB
While it is true that the Chart of Accounts does not show the department name, the Trial Balance does, if you make the primary sort by Department. For most users, the Trial Balance has everything that the Chart of Accounts has - just make sure to Include Accounts with no Activity. You would then just ignore the figures.
That being said, it wouldn't be a bad idea to include the department name on the Chart of Accounts when the primary sort is by department.
