I'm not sure I follow...
Am "assuming" by the list on the left, you mean the sidebar.
The selection you make in the sidebar, is what is going to be displayed on the top of the Finder window.
Sorry, but you can't have 2 locations selected simultaneously.
Either your home folder is the current location or the root (MacIntosh HD) is the location.
If you open Finder via the icon in the dock, it opens with your home folder already selected as the current location.
If you open Finder by clicking on the MacIntosh HD icon on the desktop, it opens with the hard drive already selected as the current location.
