Reverse Application of Payment to Specific Invoice

I’m currently up our A/R accounts and in the process have discovered that many payments were applied to the incorrect invoices. This has happened in periods that have since been closed. Is there a way to clear the invoice settlement and reapply the payment to other open invoices without reversing the payment?

If not closed, u cud reverse an entire GROUP/BATCH in E-10.

CLOSED = CREDIT memo processing to credit to wrong invoice, then apply credit to correct invoice
Enjoy!
