Because Ubercart doesn't (that I'm aware of?) support transaction refunds, adding this functionality is not a high priority currently. If you have a use case or business need for it, please post a response below and let us know how you'd like it to work.

From http://www.paymentexpress.com/technical_resources/ecommerce_nonhosted/px...

PX Post is capable of handling refunds (credit) transactions, however you will need to match the original Purchase or Complete transaction for this to happen. The matching is done with the DpsTxnRef given from the response of a purchase or complete transaction. You are able to do multiple refund transactions to the maximum amount of the original matched transaction.

Ubercart provides an API for gateways to do refunds, and the uc_dps_pxpost (dev) module implements it.
