There are 2 ways to print partner overdue invoice payments :

1.  On the partner for, payment follow up tab, print overdue invoices.  This report is correct in printing only the overdue invoices but we must print one at a time per partner.

2.  In my Follow ups sub-menu from Sales, select all partners with overdue payments filter, click to select all partners and from the Print button select overdue payments.  This is handy in allowing us to print all overdue clients but it unfortunately includes all historically-already-paid invoices, current invoices and overdue invoices.

How can I fix this?  I know it has something to do with making that report select only overdue and unpaid invoices but I don't know where or how to do that.  

Please help
