How to adjust white balance manually using white/gray card in canon g1x mark iii?

It is explained pretty clearly in manual:

Is it possible to do this using one button? I need WB adjustment for underwater photography and going through a few steps is eligible uncomfortable.

Shoot RAW and fix it in post.

There is an underwater scene mode, which will adjust the white balance.

The underwater scene mode works good around 3-4 meters deep. In the deeper places, the photos are blue and need manual adjustment
