Auto White Balance options

As is becoming common these days, the D4 offers two different auto white balance settings, one option that balances for a "neutral" white (AWB1), and one that balances to preserve the color of a white illuminated by the predominant light source (AWB2). I like the capability and the results, but I wish there were a quicker way to jump between the two settings -- you have to choose which type of balance you want within the menus rather than as a white balance option you cycle through.
