Setting default customization when it can't be set through menu maintenance

I have customizations applied to the Process Payments and Restart Process Payments check print screens. Applying the customization to Process payments is easy enough through Menu Maintenance, but I can’t figure out how to apply it to Restart Process Payments. I’ve created a menu item, and set the ID in Process Calling Maintenance, but in Menu Maintenance the the customization cannot be selected. Restart Process Payments uses Erp.UIRpt.ProcessPayment.dll, but with Rpt.ProcessPayment.RestartProcPaymentForm

I even tried adding the -c argument to the menu item through an updatable BAQ, but it has no effect and Epicor removes the argument on next restart.

Setting the argument in an updatable BAQ actually does work. I had a typo in my argument…
