Transmit AOV checkbox missing in Arnold 5?

In an older version of Arnold, there's a "transmit AOV" checkbox under the Transmission tab of the aiStandardSurface shader, but in Arnold 5 it's been removed. Is there still a way to achieve this or has it been completely removed? Currently everything behind glass shows up in the transmission AOV, giving me much less control.

I am lighting cars models and would like to have control of light group AOV's that are behind glass (headlights, windows, etc). Also I'd like to leave the glass with the correct alpha so I can composite it over a background.

Thanks!

Transmit AOVs was added in Arnold 5.0.2 (MtoA 2.1.0) and it's still there in the latest MtoA/Arnold

Thanks, I found out that the latest version wasn't installed on my machine at work, so it was defaulting to 2.0.1
