Blocking on Automatic Trading Commands

[Mustacheion]

I am trying to establish a fairly complex automated trade route, and have become rather annoyed at how each command blocks until it can be fully fulfilled.  For example, if I don't have enough money to buy the specified quantity of a good, the ship just waits instead of moving on.  Likewise, if there aren't enough goods to buy, the ship waits until there are.  To me it makes sense to attempt to fulfill each command, but then move on to the next one in the chain.  i.e. buy as much of a good as you can, then move on to the next stop, instead of waiting around forever.

 

Do other players like this blocking behavior?  Or is this done for balance?  Seems to me like it makes it way harder to set up trade routes, as you have to be so precise, which in turn forces you to be much more conservative with the quantity of good you move.
