Currently, on the "Services" screen, it is possible to rearrange each service individually, but it is not possible to move them together as a group by parent service. Consequently, if you want to move a parent service along with its child services, you must manually move each service one by one. This process could unintentionally alter the structure of the services and could potentially cause errors.
Therefore, I would like to request the addition of a feature that allows the movement of a parent service along with all its child services in one go. This would make reordering services more efficient and safer.
