How can I add an "International Supplier" filter on the out of the box control?

Summary:

I can't relate the "Supplier Site Location" object with the "Audit - Supplier Bank Accounts" object to add an international supplier filter on the out-of-the-box control.

Content (required):

I need to add a filter to the "60007: Changes to Supplier Bank Accounts on a Weekend" control to make it consider only international supplier. I tried using the Audit objects ("Country Old" attribute), but it didn't return incidents. I think the ideal is to use the "Supplier Site Location" object, but I can't find a way to relate this object with the "Audit - Supplier Bank Accounts" object.

Is there a way I can create that filter not using only Audit objects?
