Is there a way to edit OE invoices in AR?

We use OE module to create invoices selling stock and non-stock inventory items from IC module.  Sometimes there are errors on the OE invoices that need to be changed such as wrong taxes charged, unit prices don't match customer PO, etc.  Sometimes the customer has returned the invoice and asked to have something even as simple as the ship to address modified but does not want a new invoice.

In the AR Setup > Options screen, there is an option for "Editing external batches" which I have checked.  Now I can edit unposted OE invoice batches in AR.  My challenge now is to be able to print the modified OE invoice from AR but have it look like an OE invoice.  Is this possible?  I don't want to change items but may need to change selling prices.

Is what I have described even possible or do I have to go back to creating "dummy" invoices in Excel/Word?

Thanks in advance for any help offered.
