There are two things you can set up using the Region inspector: settings that affect whatever region(s) is(are) currently selected, or if no regions are selected, default setting that affect any new region of that type (either MIDI or audio) that are recorded on any track.
However you cannot have default settings that are different depending on the track, no: MIDI default settings or Audio defaults settings apply, respectively, to all MIDI or Audio regions recorded on any track in the project.
