Translation Using Country Code Using Bing Translation API

Hi,

We are using Bing Translation API from the Microsoft. We have two languages ( fr-CA and fr-FR ) which we want
 to translate from en-US. Currently in the translation API we can only pass the language code and not the country code for the translation. But these two are different ( fr-CA and fr-FR ) languages and should have different translation.

But in the API we can only pass fr so translation for the both the language ( fr-CA and fr- FR ) will remain same.
Bing translation API supports zh-CHS and we can pass CHS with the language code in the API.

So is there any way that we can translate using country code also using Bing Translation API?

Thanks for any help.
