Purchase Order header level tolerance

Hi Team,

We have a requirement to apply receipt tolerance at the Purchase Order header level instead of the line level.
Our business wants to receive goods based on the total PO quantity, not per line.

For example, if the PO total quantity is 100 and the tolerance is 5%, we should be able to receive up to 105 units in total.
This should apply only for a specific Buyer and Document Style.

Please let us know if any setup is available or if this can be considered for a future enhancement.

Thanks,
Sagar K
