Auto refunds to account balance for partial payments

This is a small one, but currently we have every transaction that undergoes an auto-refund set to the destination of the account balance. This works flawlessly until the system encounters a partial payment. If the system sees a partial payment it gets put into another list where staff needs to go and manually check that something has appeared, and manually refund both charges to the account balance. I've brought this up many, many times over the last several years, but I can see how if some cc charges go back to the cc or some go back to the account balance that you would want a human checking that. That seems like a nice OPTION to have, but not something I want to be forced into doing. The software is creating chores for us when we want to make it as easy on the software to dump all auto-refunds into the account balance. There is already a very useful solution the team has made with the ability to revert refunds if you want to change things later which is great.

So, what I am proposing is IF the destination of all auto-refund is the account balance, THEN auto-refund ALL charges regardless of payment origin. The system can handle refunding a cc charge and a balance payment on separate bills, but somehow it cannot handle it if it's on the same bill. Please and thank you!
