Grant refunds should create adjusted amount on the same grant record.
When recording a grant refund, the system creates a new grant record that is negative rather than reducing the paid amount of the grant being refunded. If a payment is intended to be reissued, it would require the user to create a whole new grant entirely rather than just adding a new payment on the same grant. The fund advisor on the portal will then see the original grant, separate grant with a negative amount, and a new grant for the re-issuance. This is also inconsistent with how scholarship refunds are handled which reduces the scholarship paid amount and requires the user to apply payments or reschedule payments to add up to the remaining scholarship amount after the refund. Based on inconsistencies with other refunds in the system, requirement to create an additional new grant, and how it displays all the ins and outs to the fund advisor whish is avoided in other areas of the system, this should be updated.
