Currently, sub-processes are displayed in the order they are created. This creates a problem when the workflow needs to follow a specific handling sequence. To change the order, sub-processes must be deleted and recreated, which is inefficient and error-prone.

It would be very helpful to have an easy way to rearrange sub-processes (for example, drag-and-drop or move up/down controls) so they can reflect the correct operational order without needing to delete them.
