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.

Hi!
I’m trying to do basically the exact same thing: use a game controller to change lens settings with user inputs.
Did you ever figure this out? In my blueprint I’ve gotten as far as having the controller input get all actors of the CineCamera class, but after that I have no idea what node to call to allow access to the iris/focus/focal length (etc.) settings.
