Ability to assign tractor/harvester to specific farms.

Any chance you can add the ability to assign specific tractor/harvesters to specific farms like assigning trucks?

I have set up 3 farms (3 different farm buildings and 3 fields around those farms) and all my tractors go to the first farm I started and none work the other 2 farms to start. I hope they will eventually go to the 2nd and 3rd farms once they finish with the 1st farm.

added in 1.6.0 :) open the farm window, under "farm machines" you can assign tractors and combines with + / - like at a mine tower. assigned ones only work that farm. before that they just stayed at the farm they joined first, thats why all went to your first one
