How to setup supplier payments through intermediary bank?

Summary:

There some suppliers whose bank accounts do not have SWIFT/BIC code, so, whenever we try to pay them via host2host (using our templates on Oracle: 

Wire ) these payments fail and have to be entered manually by Treasury.

We would like to know if a rule can be added to the XML file sent to CITI bank platform stating that every time the bank account of the supplier has an intermediary bank, the recipient bank information (

Routing number

 and 

bank account)

 should be forwarded there using the SWIFT CODE (see picture "Oracle - Bank creation fields").

We would like to create this so all manual payments that are made for international suppliers can be included in the host2host one. Hence, reducing AP clerks time wasted in creating these payments separately and forwarding them to Treasury so they can, again manually, post these payments.
