Are you running your import in Validation mode? If so, here's an excerpt from a previous forum post:
Just to clarify - you would like to see the incoming gift information when you open the duplicate matching screen, is that right?
Please let me know if that's not what you meant. Also, I'd recommend posting your idea on our suggestion site, iom.uservoice.com!
Thank you!
