Add last four of CC# to Order Summary Page

Good day all,

I'm looking to see if there is a mod or someone with experience in modifying the columns that are available in the order summary page (click on orders and see rows of orders, as opposed to clicking on the row to see the details). The issue is this. If there is a customer that orders a product, the merchant (Moneris) provides a report that has the date, amount, and customer CC#. Zencart shows in the order page the date, amount and customer name. When there is only one order in a day for an amount, all is good, but if several people have orders for the same amount, it is tedious trying to match the Moneris report to Zencart. The solution that I am looking for is to add a column to that screen that has the same last four of the CC# that the detail screen does.

I've been digging through the code, but it is complex, and so I figured I would check in with the community to see if anyone has a solution already before I start touching pages I'm not qualified to mess with :blush:.

Thanks all!

FWIW: ver 1.3.7
