Caretakers have many options of what to do. They can
* repair own or allied damaged things,
* build own or allied unfinished things,
* start reclaiming own things,
* reclaim unfinished things,
* reclaim wrecks,
* maybe more I forgot,
and I have an idea which caretakers should do what in which priority, but I don't know of a way to configure it, so I have to fight the UI to try to manually micro them. Is there a way to tell caretakers which priorities they should follow?
