Is there a way to route 2‑way and 3‑way match PO invoices to a designated user?

Summary:

The routing issue involves differentiating invoice lines based on PO match type. Invoices containing only 3‑way matched lines auto‑approve correctly; however, invoices that include a mix of 2‑way and 3‑way matched lines are also being auto‑approved. This occurs because the existing 3‑way auto‑approval rule triggers whenever any 3‑way line is present, without excluding invoices that also contain 2‑way lines. As a result, mixed‑match invoices bypass routing to the appropriate Buyer. Adjusting the rule to stop this behavior prevents fully 3‑way invoices from auto‑approving, indicating the current logic does not explicitly require the absence of 2‑way lines before auto‑approving 3‑way invoices.
