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
	;;

        down) ;;
