There are plans to improve referring in general. Those plans include having some kind of tracking added to pfq.link links (the ones used on Display Codes and the Profile links on your Party page) that will identify you as the person who got the visitor to PFQ in the first place, that may lead to auto-filling the referral box.
Point is, it's in planning stages.
