I think looking in the commerce application project you could have apps->customer->Config->View with a whole load of XML views. You need to add the field in as an item XML element. I'm not sure which of the views it is, you'll have to experiment
I would suggest to add a metafield to your Contact class, and update that field when an user logs in. Then you can use a new view which include that column
Doing like Scott suggested is of course one way to go, but it's not trivial and not officially supported (grey areas). And it is tricky if you use something like AspNetIdentity
Thanks for the input Quan Mai!
Is there a way to add that column to the view programatically or do I have to do it manually?
In the Customer list view in Commerce Manager my customer also want to see last login date as a column.
Last login Date is availible on the account connected to each customer, But how do I get that column to show in the list view? That field is not availble in the list of fields to add.
