Route only adult content through VPN route

I'm in one of the states with the age verification ban on adult content. I have a UDM Pro and have generated a valid and functional openVPN config file that works perfectly when all traffic is set to be forwarded via the Policy-Based Routes.

I want to only route adult traffic through this specific VPN config. Adding just "pornhub.com" and "www.pornhub.com" doesn't allow access to the site. I've found some adult content blacklist and tried to import those into those domain names into the destination field but somewhere is 10s of thousands of domains there are domains that Unifi doesn't like and I've done some regex searches to find potential issues such as comment fields buried in there but even after cleaning up, something isn't right. I've tried importing as .txt and directly copy / paste into the batch add box.

So my request is this, does anyone have a clean .txt file that Unifi will accept or any suggestions on how to get this to route correctly without sending all of my traffic.
