Approval User 2 date to be included in list of fields

Currently there is no option to see when the Approval User 2 has approved the invoice in the Payables Summary. The list of fields contain only Approval User 1 Date.
We need option to capture the date when Approval was done by the second user. Ideally there should be option to capture and view the approval logs of all the list of users who approve the invoices, in the LIST page.
