[Mailman-Users] Central address for handling requests?

Is there a way to setup Mailman for a single email address (eg. listrequest@host.com)? My company used to run listproc, which has a single email address to handle all incoming subscription requests, which is very nice when the email interface needs to be as user-friendly as is possible. Is there a way to accomplish this in Mailman instead of having separate <list>-request@host.com addresses?
