Can I do this with -request addresses

[Software Development <junkyard @ primate . wisc . edu>]

Can I do the following when I have majordomo listening on a -request
address for a list:

1) Send a specified file back to the person mailing the request, rather
than the usual boilerplate message majordomo sends back.

- or - 

2) Respond to recognized requests, but forward unrecognized ones to the
list owner, rather than bouncing them back to the person mailing the
request.
