You can already set factory rally points at the teleporter. Is that what you are talking about? Or do I just need my morning coffee?
The coffee thing. I took it to mean you can’t currently specify the route an army will take to reach a teleporter, because the use command wipes the queue.
same for pelicans: their pickup is limit only to last issued, e.i. you cant queue the same pelican to pick and drop off a unit, and than pick another, that overrides the whole thing. But it would be fun to have units patrolling from teleporter to teleporter, i think you can go around that by setting a mid point move command, and than a use command to the next tele
You can rally teleporters into each other if you use the "use" command directly from the tele. Sometimes my tele shenanigans get way too complicated.
