[exim] Different ports on a manualroute router?

Hi,

the manualroute router allows to set a list of hosts to try in
sequence or random order when delivering a message. Is it also
possible to specify a port to connect to on the remote host?

I'd like to have a rule like "try port 25 on host A, if that fails,
try port 587 on host A, and if _that_ fails too, try port 25 on host
B", so setting the port option on the transport is too global.

Any hints will be appreciated.

Greetings
Marc
