Issues with refund process

Process 1. From Sale Screen - This process is okay for returns based on quantity per product, but, this return transaction does not get tagged to a specific costumer. Therefore, this transaction does not appear in Invoice List Reporting for a specific costumer. It is very important that this return will be tagged to a specific costumer for recording and audit-trail purposes.

Process 2. From Sales History - This process is NOT okay for returns based on quantity because you can only either cancel the whole line item or not. But, this process tags to the customer and appears in the invoice list reporting, unlike process 1.

Suggestion 1. Enable Process 1 to tag specific costumer or just tag it automatically based on Receipt Number so it appears in the invoice list.

Suggestion 2. Enable quantity based refund in Process 2

Thanks.
