I would like to see a trade-route system upgrade.
Currently, if you wish to create many traderoutes that are the same, e.g. capital to troop town next door, or feeder to troop town, you have to enter in 6-24 trade routes.
Enter in 1 trade route, then select via radio button or tick box which hours you wish that trade route to execute. This means you only have to make one trade route for each resource allocation and then it will repeat it at whatever hours you wish throughout the day.
If you wish to change the resource allocation for that traderoute, you only have to do it once.
If you wish to change the hours that the trade route, you just untick boxes.
It would mean that setting up trade routes goes from a 30min job to a 2min job, per town and make the game a lot cleaner.
