How do I get a "Ground Consumption" option listed under the fuel tanks loading section?

You will only have a "Ground Consumption" option listed in the fuel tanks loading window if you have a ramp weight limit set up on the SETUP page.

To set up a ramp weight limit, open your W&B profile and go to SETUP > WEIGHT LIMITS and tap on RAMP.  Enter a weight in the Ramp field.  If you do not have a published limitation, simply enter a value equal to your Maximum Takeoff Weight.

You will now have a Ground Consumption field listed under your fuel loading section.
