I have a POST endpoint that takes a URL path param and then the body is a list of submitted DTOs.

So right now the request DTO looks something along the lines of:

```
[Route("/prefix/{Param1}", "POST")]
public class SomeRequest
{
    public string          Param1  { get; set; }
    public List<SomeEntry> Entries { get; set; }
}

public class SomeEntry
{
    public int    ID    { get; set; }
    public int    Type  { get; set; }
    public string Value { get; set; }
}

```

And the service method looks something like:

```
public class SomeService : Service
{
    public SomeResponse Post(SomeRequest request)
    {
    }
}

```

If encoded via JSON, the client would have to encode the POST body this way:

```
{
    "Entries":
    [
        {
            "id":    1
            "type":  42
            "value": "Y"
        },
        ...
    ]
}

```

This is redundant, I would like the client to submit the data like this:

```
[
    {
        "id":    1
        "type":  42
        "value": "Y"
    },
    ...
]

```

Which would have been the case if my request DTO was simply `List<SomeEntry>`

My questions is: is there a way to "flatten" the request this way? Or designate one property of the request as the root of the message body? i.e perhaps:

```
[Route("/prefix/{Param1}", "POST")]
public class SomeRequest
{
    public string          Param1  { get; set; }
    [MessageBody]
    public List<SomeEntry> Entries { get; set; }
}

```

Is this doable in any way in ServiceStack?
