Just having a function that returns the current route from the RTJson object would be enough for me.... once I get it, I can parse the json object, modify/remove headers as needed and then relay the call.

If there is no function/method/static variable available in the module, wouldn't that make sense to have it? just asking....

It sounds like your use-case might require going outside the boundaries of the `rtjson` formula, and perhaps retrieving and consuming a JSON route set manually.
