自定义OpenApiResponseWithBody组合属性实现失败，求解决方案

我需要在Azure函数应用中创建一个自定义属性，将重复的OpenApiResponseWithBody属性整合为一个，避免每个函数都重复添加如下属性标记：

[OpenApiResponseWithBody(HttpStatusCode.OK, "application/json", typeof(SampleResponseDto))]
[OpenApiResponseWithBody(HttpStatusCode.InternalServerError, "application/json", typeof(SampleErrorResponseDto))]
[OpenApiResponseWithBody(HttpStatusCode.Unauthorized, "application/json", typeof(ErrorResponseDto))]
[OpenApiResponseWithBody(HttpStatusCode.Forbidden, "application/json", typeof(ErrorResponseDto))]

我期望用一个自定义属性（比如OpenApiDefaultsAttribute）替代这些冗余代码，示例实现如下：

public class OpenApiDefaultsAttribute : Attribute, IMetadataAttribute
{
    public Attribute[] Process()
    {
        var attributes = new Attribute[] {
            new OpenApiResponseWithBodyAttribute(HttpStatusCode.Unauthorized, "application/json", typeof(ErrorResponseDto)),
            new OpenApiResponseWithBodyAttribute(HttpStatusCode.Forbidden, "application/json", typeof(ErrorResponseDto))
        };
        return attributes;
    }
}

但按照合并属性的方式实现后，这个自定义属性在函数应用场景下并未生效，特此寻求解决办法。
