Is it possible to create a mod that would allow you to redirect the trade between two markets just by changing the rally point?

Currently, if we want to alter the trade between two markets, we would have to delete the market, which then the carts will gather to the original designated market until the carts are reassigned a new market. If there is more than one market after deleting one, then it would automatically begin trading with the nearest existing market.

There is a technique used in Michi which allows you to build markets close to the allied market and redirect the carts to your allied market to your "home" market on the other side of the map by first clicking on your "home" market first then your allied market without going to the ones closest to your allied market. This has to be done individually with each cart.

Are you sure about your statement? Can anyone else confirm that it's not possible?

Out of curiousity, what language is this game written in?

I confirm his words. Even as .exe patch no idea how this can be done, especially without source code.
