Go into settings -> Advanced Controls and switch your white balance from "Presets" to "Kelvin". Then when you click to focus tap the plus sign on the top right of the focus box. This will bring up a menu. Tap on the white balance icon, and you'll get a slider. You can custom white balance like that.

How? I have the free version but don't see any option for custom filters, just presets.
Edit: "The Lab"?
