emailing notification of invoices on hold due purely to receipting of goods not being done

 Hi I know there is an Alert for notification of invoices on QTY REC hold to laert users to goods receipting not being done. I have also noticed we have this hold along with multiple holds on invoices where there is a billing issue, and although the receiving may have been done correctly, the QTY REC hold is not removed automatically until the other holds are resolved.
What conditions am I looking for where the hold is due purely to receipting not having been done?
QTY REC is isolation, with no other holds on the invoice?
