Validate invoice automatically after holds released

Hi, We have invoice validation request scheduled once a day in the evening. When invoice-holds originating from matching to PO's (received, ordered, price but In fact it could be any hold) are released during the next day/working hours they only get validated once in the evening. Scheduling Invoice Validation Concurrent Program during the day/working hours means that all invoices get status "Selected for invoice Validation", which means that users cannot access/maintain invoices. We use AME for approval -and holds notifications. Is there a way to get an invoice validated at the moment its holds are released? A business event, service
