对象数组到包含所有所述对象的单个对象Dataweave

我正在尝试转换以下对象数组输入：

[
 {
    "Id": "3",
    "Code": "4190484",
    "Expense": "Huge Expense "   
 },
 {
    "Id": "4",
    "Code": "271",
    "Expense": "Big Expense"   
 },
 {
    "Id": "3",
    "Code": "433",
    "Expense": "No Expense"   
 } 
]

到这个单个对象的输出：

{
    "Id": "3",
    "Code": "4190484",
    "Expense": "Huge Expense ",
    "Id": "4",
    "Code": "271",
    "Expense": "Big Expense",
    "Id": "3",
    "Code": "433",
    "Expense": "No Expense"
}

您将如何在 Dataweave 中完成此操作？
