[GNC] Payment paid which Bill? How to see which check paid which bill?

[Fran_3]

There is no way to see what bill a check paid... is there?
When paying a bill you get 5 fields...DatePaymentRefundNumMemo
Date, Payment, and Refund won't do it.Num is for the check numberMemo could be used but that is just a visual association... 
Seems like the system ought out to have a report showing Vendor's Bill/Invoice number & date plus the Payment Check number and date...
Is noting the vendors invoice/bill number in the Memo field the only way to do it?
We considered putting the vendors invoice/bill number in the Num field but that field is for our check number...
Am I missing something obvious? (Won't be the first time :-)
Thanks for any help.
