MIDI part editor (Currently Edited Part menu) - multiple parts on a track as one single part (menu item)

I want multiple parts on a track to appear in the “Currently Edited Part” drop-down menu (see picture below) as one single part distinguishable by the track name.
It would be useful a Preferences option that would toggle this menu between:
→ “Currently edited part” (names of individual parts);
→ “Currently edited parts” (names of tracks that contain multiple events).
