How to restrict Manual and Quick payments only and allow Refund from Create Payments page

Hi Experts,

The standard Quick Payment functionality bypasses the Approval Process, and therefore the customer wants to remove the option to create Quick or Manual Payments.
However, removing the privilege Create Payables Payment is not feasible, as the customer still needs access to the Create Payment page for processing Refunds. In this case, the requirement is that the Payment Type should display only Refund.

We checked on Metalink and found that an Enhancement Request exists.
We are exploring if any alternate workarounds can be achieved using Page Personalizations. Has anyone implemented a similar solution?
