Control dimension value from dimension command


This is what I’ve got. I can make the two balls move (the distance between them is constant) along the line.

The dimension is set to show the distance between the cone and the closest ball.

I can add more cones.

Is there a way to control directly this dimension? if I want to set an exact dimension between a cone and a ball (knowing that it will affect all the other positions).
