Where is the default setting for 'Invoice Match Option' stored?

Summary:

'Invoice Match Option' is set to 'Invoice' by default in our environment. This is causing havoc on the Accounts Payable side as invoices may not be matched to the appropriate receipt since they have no visibility of receipt information except the total amount in available receipts.

I understand this can be resolved by setting 'Invoice Match Option' to Receipt. Where is the default setting stored? I want all new orders to default to 'Invoice Match Type' = 'Receipt'. Currently the buyer is manually making the change under the 'Billing' section when editing each req line in the document builder process which isn't great. This has to be done for every requisition line on the order.
