Okay... so I feel like a dummy!! If The Grim has it working, I thought it HAS to be there... at least it's supposed to be there. So...
The Reel ADT Send Level IS there (yay!), but it's separate from the Reel ADT Send Pan Level. All the other Vocal plugin sends I have in the automation lane to various busses where the plugins are have all their various automatable parameters together in a group. The Reel ADT Send Level is at the top of my automation lane drop-down (even above the track volume), and the Send Pan Level is at the bottom.
