How can I get Customer Memos to pop-up in Invoice History Inquiry?

Hi,

I have several customers with special requests regarding the sending of their invoices (mail, fax, e-mail to specific parties, etc).  We created memos that pop up during Sales Order Entry.  Unfortunately, that department doesn't always remember to make note of it on the invoice, so when the invoice comes to me, I have no idea of the special requests.  Why can't the memos automatically pop up on the Invoice History Inquiry screen?  Does anyone know a back alley way to do this?

Thanks in advance for any help!
