Nav: Record/restore preferred position on each given axis.

Browse Source 
Tagging #6344 #6003 #2694 #1688 as it relates to scoring, however this doesn't technically fix any of them fully yet.
But e.g. once we restore axial path for #2694 this commit will allow going back and forth to initial location.
