How to select A-mount lens profiles in Camera Raw ? (using nex-7 with la-ea2)

Hi there.

I took my nex-7 with la-ea2 on my last holiday, along with the sal1680z lens.

I'm using cameraraw 7.3 to bring my raws into photoshop, but the a-mount lens profiles dont show up in the list.  Only the e-mount lens profiles are there so it's like cameraraw knows that ive used a nex-7, but can't detect the lens through the adapter... which makes sense ...

Sorry this is probably a stupid question, but how do i add the SAL1680z lens profile?
