Sram force etap 2x12 shifting sensor

Connected SRAM Force etap as a shifting sensor in Fenix 6 Saphire.

I have 2x12 system (48/35 in the front and 12 speed 10/28 in the rear).

I can customise the front gears without issue.

As for the rear gears, the sensor setting is maxed out at 11 gears (no 12 gear option)

Recently there was an update to fenix 5 (18.40 which includes 12 speed gear option.

When will this update come to fenix 6?

Or am i missing something and it is already a feature on the fenix 6?
