I can't find any info on this subject. Is there any way to augment the existing trade fleets? For instance, if you add transport ships to the trade fleet, will it have any effect on trade income? Is there any way to add to trade fleets at all, or replace lost trade ships? And of course, can you then add trade ships to the trade areas that are empty?
Sorry if this was covered before, but I couldn't find any answers on this subject.
