W/B and ISO buttons

I tend to use W/B and ISO buttons alot, but that camera make me mad, because they are so hard to reach. How do you deal with that?
Thanks

Menu f6 works for me. "release button to use dial". Press the iso button once with right hand, then move right hand to the wheel to change iso. This is helpful when I have the big lens on and need to always support camera with my left hand. I only need it for iso, but it works for wb. I shoot raw, so I dont mess with wb. You could look into 'easy iso', I don't care for it.

I shoot raw with auto WB. So if the WB is off, it's an easy correction in post.

I shoot raw with auto ISO. If the ISO gets too high to start creating noise, it's an easy correction in post.
