Edit the Cursor Motion

In the Design view select the cursor motion in the timeline you would like to edit. In the panel on top of the scene, you will find cursor options. Select the Path icon and select custom. Now you can move the start and end points of the cursor path anywhere you like. On the cursor path there is also a little triangle, click and hold on this then move your cursor in any pattern to create a new custom path for your cursor.

Be careful; if you select a cursor motion by clicking on its path in the scene while the Playhead is in the middle of it in the timeline, you erase your custom path. To be safe, select the cursor in the timeline or by clicking on its start or end points in the canvas.
