Access TLS certificate distinguished name in rsyslog conf

Question

I have the following rsyslog config file 10-custom.conf in which I want to have access to the distinguished name (CN, OU, L etc.) of the TLS client certificate that is used to establish the connection to rsyslog.

module(
load="imtcp"
StreamDriver.Name="gtls"
StreamDriver.Mode="1"
StreamDriver.Authmode="x509/name"
PermittedPeer="peers.mydomain.com"
)


$DefaultNetstreamDriver gtls
$DefaultNetstreamDriverCAFile ca-root.cer
$DefaultNetstreamDriverCertFile rsyslog.cer
$DefaultNetstreamDriverKeyFile syslog_private.key

ruleset(name="tofile"){
    action(type="omfile" file="/var/log/test.log")
}

input(type="imtcp" port="1514" ruleset="tofile")

Is there a way to access the before mentioned distinguished name properties for log processing? E.g. passing logs to different hosts depending on the common name? Non-working example:

if ($commonname contains "client1") then {
   action(type="omfile" file="/var/log/client1.log")
}
if ($commonname contains "client2") then {
   action(type="omfile" file="/var/log/client2.log")
}
