Would be Nice if New Windows Opened Groups Above a Placed Separator

I am able to make Groups (Saved Window) but, when I open & close chrome, a new group is created at the bottom of the list, below my created group (saved window).  After opening & closing chrome a few times, my saved window/group gets lost among many new groups.  If I create a separator, it makes no difference, new groups continue to be created below the separator.
