EDI Location code at supplier header

Hello Experts

Is there any flag or field at supplier header to input EDI location code? I know that there is one at supplier site in Address tab but this may not be a great use to use as we have 100+ supplier sites  for most of our suppliers and setting this flag for every supplier site is going to take ages.

I can see that there is a column called EDI_TRANSACTION_HANDLING in ap_suppliers table but I cannot see the equivalent field from suppliers page.

Please advise

We are in R12.1.3

Thanks
