Customize the Payment Report ?

On the payment report under reports, can you add any fields? I'd really like to see a notation if it was an affiliate sale or a regular sale.

thanks in advance

Thanks. Is there a way to have the invoice number on the exported report? it's not in the dropdown list for options when exporting.

I think if I can get the invoice number on the payments report, I can then use that with the affiliates clicks in an excel spreadsheet and cross reference.

Or is this something for the suggestions for updates/future versions? Thanks again!
