I'm using Panels to overwrite node template (node/%node). I would like the system to use specific variant when a node is loaded. E.g. node 123 should use variant A and node 223 should use variant B. There isn't an option for me to determine that under Selection rules, I'm wondering if I should use PHP Code, and if I do, how should I go about writing the code?
I'm aware of the option of using Panels Node, but by using it, there is no easy way to edit the node thus rendering it a less than desirable choice.
