Force/ignore task

Hi there! Loving the build so far, really cool.

One thing though, is there a way to "forbid" a construction, or force a dude to build a particular thing?

Everyone was starving on a run, I tried to build a kitchen but they wanted to continue building other stuff instead.

Yeah, there's a "priority" button, but I'm not sure if it does anything yet. I was trying to get a power node built so I could turn on the heat and even though I had priority set on it, they just kept building walls.
