[exim] Something like "domains_require_tls"

Hi,
for legal reasons I have a list of domains, where I *must* send via TLS
Currently, I have two routers and transports:

router_A:
    domains: +domainlist-with-TLS-Domains
    transport: tlssmtp
router_B:
    domains: *
    transport: smtp

tlssmtp:
    hosts_require_tls = *
    driver = smtp
smtp:
    driver smtp

in reality two routers and transports are much more complicated but almost
identical. The same is true for the transports.

Is it somehow possible to consolidate this into one router and one transport
and lets have in the transport "something like"

domains_require_tls = +domainlist-with-TLS-Domains

I now that this option does not exist, but is it possible to configure
one router and one transport that act like that ?

Regards, Olaf
