how do i change the CineCamera lens setting

Okay so what im trying to do is make a film camera to run around with in the game, I want to use the cineCamera because it has all the setting I need.
I want the ability to change the lens and focus and have both of these displayed in the HUD. Also for a Zoom lens i would obviously want to be able to change that too.
The bit I’m stuck on is how do I change from one option in the pull down menu to another, specifically the options under Current Camera Settings. I want to be able to use the D pad to cycle through the different options.
