Referral Source

There is currently no elegant solution to associate one contact record as a referral for another contact.  The 'workaround' offered by the Hubspot community does work (creating 2 custom fields to ID and enter a referral soure onto another contact record), but it would be easier if Hubspot built this functionality into its platform. 

 

It would require a field on a contact record that is a lookup of other contacts (probably labeled "Referral Contact").
