Having placed many balloons automatically, you may decide to reposition one or more balloons or balloon leaders.
In this case, the leader for balloon 1 (which identifies the base) needlessly crosses over the cylinder. In the following steps you move both the balloon and the leader arrow.
As you drag downwards, notice the vertical dotted line appears, indicating that your balloon position is aligned with balloon 7.
Next, you adjust the leader arrowhead position.
