Way to assign cleaning areas?

[DreadZep]

I know that my colonists will clean anything in the home area but the problem with that is its also the only way to get them to fight fires automatically. so if i delete home area for a remote geothermal plant and a fire starts around it, if its in the home area it gets dealt with, if its not it burns down unless i make them do it manually. mainly its the power conduits to these areas that are the problem. i dont want to asign them as home areas because then it becomes a problem for someone cleaning up the ouside enviroment at extremely remote locations and taking up the majority of their productivity. the obvious solution is just to add an area for cleaning and for fire fighting. and while youre at it just get rid of home area and make gathering areas and trader areas.. i mean why not?
