How to Update "Invoice Match Option" on ALL Vendors

We have changed our business process of doing a 3-way match to a 2-way match.

All our vendors are set up with "receipt" as the default Invoice Match Option. We need a way to update all of our vendors to "Purchase Order". The only way we see how right now is to do it individually... that is over 2K vendors. Since the supplier screen is browser based we can't do a DataLoader.

Does anyone know a better way to do this?

Thanks!

(we are using Oracle EBS r12)
