How to change the FOV of Brueprint viewport?

I know the FOV configuration of main viewport for World preview can be accessed from the top left button.
Viewport Options

But, How about the blueprint viewport?

Don’t think there is such an option.
-You either change the FOV for camera.
-To do a quick preview you can hold right mouse and while flying in viewport press z or c to change fov.
-Maybe expose the editor func.
