[exim] QueryProgram Router Question

For better or worse, I am using the queryprogram router to evaluate incoming messages against a complex set of rules managed by an external application. Currently, I am only getting the message body piped to my external program and I have to pass the SMTP header via a command line switch (gross). I am wondering if:

(1)    Is there an option to pass the entire message via the pipe (modified headers + body)?

(2)    If there is no such option can I make that a feature request?
