Separate Dump Tower instead of combining mining and dumping in Mining Tower.

I think there should be a Dumping Tower that is separate from the Mining Tower. Without watching videos and tutorials, the use of the Mining tower for both is confusing for new users and annoying to me and possible some other more advanced users.
In addition to the button that sets the area, there should be a button that I can press to set the Dumping or Mining in each tower. Doing this elsewhere in another dialog not directly attached to the Mining Tower makes no logical sense to me. I always want to click on the tower to do everything needed to either Mine or Dump at the area of infuence of that specific tower.
Right clicking a Tower and selecting from a couple of options related to the Tower would also be helpful. Like context menus in Windows.
With a warning message that reminds me that I need to refine the Dumping/Mining instructions. This might prevent the annoying messages on the right side of the screen that tell me I forgot to set mining instructions for a tower.

why not just build another tower ?
