Paid Gateway column

When we offer clients multiple ways to pay, it would be great to have a column in the invoice list view (dashboard) that showed which Gateway was used, together with the paid date/time. I know this can be found in the single invoice view, but for accounting and admin purposes it would really help t have this info at-a-glance. Ditto for the CSV export, if it could have its own column in the export, would be very helpful. Thanks for your consideration.
