Well, for a single host, it would be something like this:
any: host 10.10.10.10 gateway 192.168.1.1
But the question is still whether or not NetworkManager will obey this file.
Worst case scenerio we can write a NM dispatcher script to do it:
in: /etc/NetworkManager/dispatcher.d/
create a file called static, chmod 755 static, and add: (NOT tested): I ripped the section from /etc/init.d/network.
#!/bin/sh
interface=$1
state=$2
case $state in
up)
# Add non interface-specific static-routes.
if [ -f /etc/sysconfig/static-routes ]; then
grep "^any" /etc/sysconfig/static-routes | while read ignore args ; do
/sbin/route add -$args
done
fi
