Did Melodyne Editor's Vocal Alignment feature disappear?

I'm trying to sync some backing vox but I just can't find that "source track" or whatever tab anymore - it used it be right there in the quantize box.. Has the update taken it away perhaps?

Craig, I am 99% sure Editor had a similar feature to Vocal Sync, where you could reference another track - it was in the quantize tab. I did not use it often but today I can't find it. Maybe I've finally lost my mind - it was inevitable! :)
