Hi what flag should I use in the devices.rzml to set the squeeze on a camera in MM4?

Hi, could I just point out as well that I don't mean then pixel aspect ratio but the other squeeze value.
I want the PAR to be 1.422 but squeeze to be one.
If I set the PAR to 1.422 using
a="1.422"
it also assigns that value to the squeeze (in matchmover the value next to the 'Type' field and above the film back unit field).
