Panning ArcRotateCamera with keyboard without using Ctrl Key

The ArcRotateCameraKeyboardMoveInput has no option for make the default keys events (up, down, left, right) to pan the camera instead of rotate it, like when you pressed Ctrl + move keys (it activates panning).

There is a _ctrlPressed variable on the object but can’t be setted, because it will be updated when pressed Ctrl on scene.

Is there a way to make the default movement of the camera, with the direction keys, will be panning instead of rotation?
