How can I see which registrants have paid for my event through paypal?

Can I include payment information when I export a report with submission data? I want to know whether they clicked through and completed the indicated amount due through paypal.

I can look this up in paypal, but I have many things funneling through paypal and it's complicated to sort through what's what.
