I've been dreaming of a force job override right-click option for a while, it's specially useful for cleaning and building walls fast. Basically you select one of your guys, right click the applicable work (a rock marked for mining, a wall marked for building, a dirty floor, etc) and you FORCE that little fucker to do that same kind of work for a while (say, half a day), instead of a single time, which gets really annoying really fast.
I suppose you could have a priority zone, similar to the one in banished. It's simple but it works. Basically you drag a zone that gets prioritized, then you can keep pulling those zones and you stack priorities until they are all done. Pretty useful to get one or two types of stuff done fast.
Both are viable and both should be implemented fast.
