There is no save like that. The trouble i could see with such a thing is that you could switch config's like that, but once you swich, your automatic guy's will head out and supply the other ts's real fast.
Things i see that might help you with headaches at first are.
Dock supply, the ts needs a dock as a homebase.
Carrier Supply, the ts needs the carrier you want supplyed as a homebase.
Self-supply, The ship will fly to the dock you tell it as long as it doesnt have to go through a enemy sector. If it say's it cant find a safe route to supply at, that generaly means there is a enemy sector he has to go through to get to a dock.
If you get a message saying that the ts you set as a carrier supply cant do it, chances are his homebase isnt set, same with the dock supply.
Also, make sure you tell your eq dock to be a supply dock. Or you will get a error saying your dock supply cant do it.

The mongrels will never get over THIS wall.
