Blacklist for Farmhands to deliver certain farm milk to you.

Quality of Life

To save on some of the inter-farm drama, and because it is impossible to blanket ban every farmhand working for specific farms, i would like to see the ability to blacklist farm milk, meaning farmhands cannot deliver to an owned dairy from a blacklisted farm. this of course to save on creating more drama should only be a setting that the farm owner can set, not managers. Thank you for your time.
