Referral Tree
Presently, there is no way to create a referral tree, or to pull a report of contacts who have referred others.
EX: If Amy refers Dave, I can enter Amy's name (as text, not as a link to her profile) on Dave's profile as a 'Referred by', and I can pull a report that will give me 'Referred by' and 'Source' (which would pull Dave's records), but I can't pull a report that will pull Amy's information.

The ultimate goal is to pull a report to see which contacts referred other prospects/clients in the past year, because we want to host a referral event as a thank you.

This will also help with ROI reports.
