on-account created by credit memos

Good-day,

Our scenario:

R12

Receipt is entered, and using auto cash rules automatically applies against the oldest invoice, and the invoice is fully paid. This is good.

Later a credit memo is issued agaist the fully paid invoice, and an equal amount of the credit goes on-account.

Is the a way for this on-account amount to automatically apply against the next oldest set of open invoices?

Please excuse if this is answered somewhere already, but I can't find it...

Thanks

-John
