Thanks so much @bezo ! I found a different solution but this is very handy. I appreciate you taking the time to help.

Use an Object list and drag in the null with the user data. Pump that into the relative link to the light parameters you're controlling and its done.

I'll start with saying I have a hard time wrapping my brain around xpresso so I'm hoping to find a solution for a setup I have. As you can tell this screenshot works but I'd love to know if there's a better way to do this via a hierarchy so I can add/remove lights as needed.
