Send Invoice number to PayPal

When a PayPal (standard) purchase is made by a contact using a different email address than their contact record, the only way to find the purchase in PayPal (e.g. for a refund) is to ask support to look at the backend purchase and give me the name of the PayPal account that made the purchase.

If the invoice number (or contact email address or  other unique identifier) was passed to PayPal during the purchase, I could search PayPal for that purchase.
