A very easy way to introduce overland trade routes

[Rodak Polak 595]

It's not exactly a trade route but maybe its possible to a add province value points if province is located on trade routes. In the editor, everyone could choose and mark the provinces through which the trade route would pass (each scenario may have different trade routes or trade routes may not exist at all. Depending on what the player decides). In such provinces there could be a bonus to income. For each such province there may be +1 prestige

So it wouldn't actually be trade, but provinces that can be selected in the editor, which have a bonus to income, but this bonus can be called "trade route bonus"

It*s kind of thing happened in crusader kings 2 and europa universalis 4.

Even if the province lies on the route of some trade route, then its value increases during the war.

and such provinces also allow epidemics to travel :))
