QC Controls Not Working on MIDI track

I am creating an orchestral template, and have each instrument set up with one instance of EW Play, and each articulation as a separate MIDI input in the same instance.

I’ve set MIDI CC11(Expression) to my Quick Control knob. The CC knob is read only on the main instrument track, but not each corresponding MIDI output track, even though the inspector shows the correct CC settings.

Is there a fix to this? I don’t want a separate instance of Play for every articulation
