I've been using Auctiva for a few years now. I've searched everywhere I can think of and have found nothing on how to make FedEx display as a selection for shipping in my listings. USPS and UPS display, but not FedEx.
Just tried to create a new shipping profile, and USPS Parcel Post is still an option! I really thought it would not be an option since it is no longer available via USPS.
