Anyone have to submit T4A for Canadian Vendors?

 We have independent sales reps and employees of our dealers that we pay commissions to...  they are not our employees, they are supplieris, but we have to submit a T4A form for them (similar to the US 1099).    Has anyone done this?  

I tested the standard 1099 function, hoping that Oracle would not include the Canadian vendors in the US 1099 report, but unfortunately if they are marked for 1099 processing they get included in the report.   At this point, I am thinking a DFF to flag them as T4A reportable, and a custom report to pull YTD balances over a certain amount.   I would love to hear if anyone else has come up with a different workaround?   I have gone the SR route through support, but the response was that the requirement is not supported.
