'Go to' water particularly caravans

[Apprentice 2 SA]

Is there anything that solved the problem of the go command being unable to cope with water in the way? I'm trying to use it for caravans. When I create the caravan I make sure it's taking the right product to the right city. When the go command fails I can't then remember where it's meant to be going!

Thanks for any thoughts.

Send your trade units to different landmasses. This gives a x2 bonus, which is the same as the demand bonus for a lot of commodities anyway. Unfortunately, keeping track of what is going where is one of the more tedious parts of the game, but it often makes sense to send everything to a handful of "good" foreign cities, regardless of what is actually demanded.
