Collabs adding a paypal email to an affiliate contact record

[bassdope]

How can I update a PayPal email address under an affiliates contact card? If this feature exists, it is really hard to find. If it doesn't exist.... please add it. Affiliates don't want to be bothered with this. Anything related to the management of affiliates should be able to be administered by the store owner. There is no good reason for locking this down. Thanks.
