Is it by design: Instrument multi-output tracks are ignored by PLE?

For instance, if I make a PLE to show all the tracks with HiHat in the name, where I’ve named some of the multi-tracks HiHat1, HiHat2, etc., regular tracks are included but the PLE will ignore the names of the multi-output tracks of an instrument track.

Is this by design, if so why?

This is partially speculation, but I wonder if the PLE only works for stuff in Project Window and not the MixConsole. Were your additional Outputs visible in the Project Window? If not, toggling Automation Write for the Track On and then back Off should cause them to appear.

Maybe post a screenshot of the PLE so we can see what’s what.
