Cisco 9500 route certain URLs down backup connection

We have an OSPF based network, but at our core we statically route some things away from our main ISP connection to another ISP. We are needing to route traffic for a group of URLs that has to many IPs to statically configure (e.g. *amazon.com) away from our main default connection to our backup connection. Most of what I was looking up pointed towards Policy Based Routing. Class map the hosts, give it a dscp value in a policy map, apply it to an access list, and routemap it to the second line. Is this the best way to go? Can it still be used in conjunction with some of the static routing we already have to the secondary connection? Appreciate the assistance.
