### 🧐 问题描述
transform 中如何返回 新的namepath ，比如：
` {
console.log("-------->ProFormDatePicker transform value:", value)
const namePat2 = ['items', itemIdx, 'answerData', 'keys'];
return {
['items', itemIdx, 'answerData', 'keys']: value
};
}}
/>`

上述不能这样 return，有什么办法吗
### 💻 示例代码

Start by tracing ProFormDatePicker's transform handling and how name paths are represented in the form APIs; the issue does not name a source file or test. Confirm whether returning a dynamically constructed name path is supported, and define completion as a documented or tested way to produce the requested nested field output.
