Curve Merging

Right click hierarchical viewport -> Shapes, then the transform will be shown.

Then select the curve want to merge, then select the target root transform node, execute maya script: parent -r -s.

Why we can’t drag the curve directly? because the drag operation will move the transform into the target transform.

Finially you can delete the child transform.
