GM1 - disabling or re-assigning WB button on control wheel?

[budeny]

This WB button is really annoying to me as I tend to press it accidentally when holding the camera and then mess up WB setting.

Does anyone have same issue or can suggest a solution?

On the GM5 there is a way to disable the directional buttons, and replace it with moving the focus box. However you do disable the other directional buttons (ISO, drive mode, focus type)
Or shoot RAW so if you mess up WB, you can always change it later
