Best way to select specific invoices during Payment Process Request?

Hello;

I'm wondering if there are more effective ways we could select specific invoices for payment each week, in our PPR's?  Today, we launch a PPR to pay eligible invoices across many vendors, based on Due Date -- but -- we don't necessarily want to pay EVERY invoice that Oracle initially includes in the PPR.

For instance, assume 3,000 valid invoices are in A/P across dozens of vendors, all of which were selected initially into the PPR (based on our criteria of Pay Through Date). 

Through our own internal A/P reviews & cash management reviews, we determine that this particular checkrun should only pay, for example, 1,400 of those.
