You want to deliver searched blood slaves to the lab from provinces with no lab?
I dont see that happening.

As to the macro thing that would be really hard for what you want. At most, a macro can make Ctrl-z into a single keypress for all gatherers at labs as far as a macro that can be used in every game you play.

A macro could be done for what you describe of course. But it would have to be recorded for every new game and those units. A single-key macro can be created for anything you can do manually. The game should not be running in a small window. The macro would have to start with hitting the HOME (to center the map on your capital) then moving the mouse to a single-pixel starting place such as the far upper-left corner of the monitor screen. At that point all actions of mouse move or keypress would be recordable and able to play back the same way every time so you woul take whatever actions you normally do to go to the province (using # and the province number is fast), then to the commanders in question and do their actions. It probably would have to be separate keypresses for "drop at lab and go to gatherer" and for "collect from gatherer and return to lab" altho it could do multiples of each. And it would be messed up easily by having a new commander in the provinces involved.

WOW even I would have a headache with that. I cant see where it would be worthwhile for gatherers that are more than 1 move from a lab, or maybe 2 moves with a relay. Obviously more useful for nations such as Pangaea and Caelum. And only then on really large maps with really old games where automating the back provinces might be worthwhile. But it would be kinda fun to watch such a macro carry out the full mission really really fast on the screen.
