Formal request for: Character containment feature

I like the drag and drop idea - allows you to place characters together for 'combined' tasks and thing like that.

My worry about solid fences is that it would really slow the game down - characters would have to find their way to wherever they're going on task without walking through things. I do agree that it looks annoyingly bad when characters just walk through your carefully placed walls and fences, but for practicality I can put up with it.
