If you've assigned them to a shop, then when you highlight their character in 'build mode', the shop will also highlight. (it will also highlight their bed).
That's obviously useless unless they happen to be standing near whatever you assigned them to.
This manages to get them past the point of "Didn't Even Try" solidly into "Tried As Little As Possible."
I'm having a great time with the game, but the settlement management is pretty awful.
