Please, add the option to use Keys Lock on both Hammond keyboards

Below is the picture

Any Hammod fan could appreciate the option to send Keys Lock chords in the lower keyboard, and grace/solo notes on the upper one, using just one Scaler 3 instance

I remember I was able to do that with 2 synced Scaler 2 instances, but if I remember well, there is no more this option in Scaler 3
