我目前调用这个API的入参是这样的

{"ewaybill_order_id":"1948297302546735105","delivery_id":"SF","ewaybill_acct_id":"6635672224","sender":{"name":"陈丽","mobile":"1896264 3896","province":"江苏省","city":"苏州市","county":"昆山","street":"千灯镇","address":"玉溪中路399号2号库B14门"},"receiver":{"name":"王**","mobile":"151****2420","province":"上海","city":"上海市","county":"中国","street":"","address":"****"},"ec_order_list":[{"ec_order_id":3729693915304040960,"goods_list":[{"good_name":"毛衣","good_count":1}]},{"ec_order_id":3729693915304040960,"goods_list":[{"good_name":"毛衣","good_count":1}]}],"shop_id":"5009834992124","template_id":"6635482112","delivery_info":{"package_quantity":2}}

出参{"errcode":0,"errmsg":"ok","ewaybill_order_id":"1948297302546735105","waybill_id":"SF1164423162831","delivery_error_msg":"调用成功","print_info":"JTdCJTIycHJpbnREYXRhJTWlnaHQlMjIlM0ExMzAlN0QlN0Q=","waybill_id_list":[],"order_risk_info":[],"changed_info":[],"create_time":1753428015}

给了两个包裹明细，但是只返回一个快递单，没有子母单返回，需要怎么修改传参才会返回 waybill_id_list 这个子母单信息？
