I seems to find a way which can do this.
First, make sure that the most recently opened folders are displayed in the home page.
Then, type "Home\XXX" in the address bar ("XXX" refers to any of the most recent folders)
At this point, it should expand out of a folder, and the expand symbol will appear next to the home folder. Click to expand the home folder and that's it.
But every time you close and reopen the folder window, the state is reset, so you need to do the above steps again.
