Change unit's homecity

<p>As Freeciv player I know the button "change homecity" or something like this, which lets the unit belong to this city from now on.This is useful, if you are democratic and want to guard a settler by a military unit. As soon as the settler arrives, the military unit becomes supported by the new city (through the change homecity command) and unhappiness gets well distributed between cities. Now I have to build every military unit in every city (time consuming) or to support several military units from one city (makes people angry). Will this feature be added?</p>
