Is there a way to re-trigger PO Account Generator when Ship-To Location is updated?

In Buyer Work Center, under Line/Schedule tab when we change "Location" to a different Organization, is there a way we can re-trigger PO Account Generator to re-generate PO Charge, PO Accrual and PO Variance Account?

The reason behind this requirement is when users change "Location" to another Organization once the PO is approved, system retains PO Charge Account but wipes out PO Variance and Accrual account and yet it allows PO to go for re-approval without these accounts. This creates issue when we try to receive item against this PO in Receiving side.

Let me know if you need any additional information.
