IDR: Report to pull Invoice Account Coding History

Summary:

We would like to track account coding history as part of the invoice for reference and audit purposes. What is the best way to accomplish that?

Content (required):

Is it possible to add the account coding history to an IDR invoice on the UI? Approval and Hold activity is tracked and shown on the invoice UI, but the account coding activity is not. We would like to have this information attached to the invoice if possible.

If this isn't possible, does anyone have a suggestion on creating a report to pull the invoice number, invoice date, assignee, date assigned, date completed for all invoices (or with an invoice number prompt)?
