Currently, when assigning vehicles (like excavators or trucks) in the Mine control tower, users must click the "+" or "-" buttons to change the number of assigned units. If a player has a large number of available trucks, assigning them all requires 40 individual clicks.

This becomes tedious in the late game or when managing multiple towers, leading to unnecessary clicking and a slower management workflow.

Hold down Shift or Ctrl button while clicking the +. Instead of 1, you will add 5 or 10.
