[Dovecot] How to configure dovecot to listen on multiple separate port numbers

Is there any way to tell dovecot to listen for imap/imaps requests on
all interfaces on multiple separate ports?

For example, can I do this:

protocol imap {
  listen = *:10143
  listen = *:143
  ssl_listen = *:10993
  ssl_listen = *:993
  ...
}

Thanks!
