If I produce a freighter at another planet can I send the freighter to my home world first so the trade route is established from there instead of where I built the ship?
EDIT - I'll answer myself since I found the answer in the next thread I looked at:

So unless it has changed, the trade route will always be from where the freighter was built. This disadvantages the super trader unfortunately since they can build trade ships from the start, but want to be building colony ships in the capital.
