An affiliate should be able to add their own contact information as a lead under themselves. I feel as though this could possibly be a pretty drastic oversight to the affiliate manager because of the frequent case of shopify or other third party integrations and services that an affiliate themselves uses and should be paid on. For example: If I am an affiliate for a store, but I also go to the e-store to make my own purchases, I should still be able to be listed as a lead under my own affiliate record.
