2x anamorphic squeeze

I have a Cinema Camera 6K. I am trying to use a Sirui 50mm 1.6x anamorphic lens with a 1.25x adapter. This gives me an anamorphic squeeze of 2.0x. However, that option is not available. Only 1.6x, Is there a way to make 2.0x as an option?

Been wondering this myself.

I actually figured it out. 1.6x is available when you have open gate selected. 2.0x is available when you select 6:5 Anamorphic
