Generate observable properties based on nested record

One disadvantage that I see with the classic observable pattern implementation is that the backing fields are accessible and visible in the intellisense even if nobody should access them directly. Have you considered to generate the observable properties based on a different input than the backin fields (e. g. a nested record)

example:
```csharp

class MyObsevablePerson
{
[ObservableFields]
private record Fields(string FirstName, string LastName);
}
```
would generate
```csharp
class MyObsevablePerson
{
private Fields _fields =new();

public string FirstName
{
get=> _fields.FirstName;
set ....
}

....

```
