options available to allow invoices to be re-coded without triggering the entire approval process?

In the current state, when AP needs to update the GL coding on an invoice that has already been approved, the invoice is required to route back through the full approval workflow—even if the invoice has already been paid. This creates a significant amount of confusion, particularly for high-dollar invoices that must route to CFO/CEO-level approvers.

What options are available to allow invoices to be re-coded without triggering the entire approval process? If only the accounting coding is being updated on an invoice that has already been paid—and the dollar amount is unchanged—could the review and approval be limited to the AP Processor’s Manager instead?
