Yes indeed, that is from where I started actually.
“Decrease Volume of Selected Track by 1dB inside Cycle”
and this preset works on all other tracks except multi out tracks.
The problem is that the PLE doesn’t evaluate the names of automation tracks of additional Instrument Track audio returns, only the main audio return (which itself is an automation track).
Bug, or missing function, take your pick. From my perspective, it’s a missing function, so maybe a Feature Request is in order.
