[Exim] Use two directors?

An Exim user would like to be able to (temporarily) have a situation in
which incoming local mail is serviced by two directors -- while switching
from one internal mail system to another, they'd like all incoming mail to
be sent to both of them.

Currently mail is sent to an AS/400 mail system under the smartuser
director. Is there any way to direct mail to *both* this and another
system (which will eventually replace the AS/400) until the transition is
complete?

Thanks!
