Every planet has a PLANET_wants group, that's put into the landing pad of that planet.
There is a buffer on each planet requesting the _wants group next to the rockets.
There are two shuttles that go through the planets clockwise and counter clockwise. They both have all the planet _wants groups
So if a planet needs huge drillers, it gets set one time in the _wants group, and everything else just happens automatically.
The ability to share logistics groups across devices is a really good quality of life improvement
