Possible to use root object in withFieldGroup component?

[mhuggins]

I've got an object type that is often nested under another object in forms, prompting me to use withFieldGroup for handling this structure as a common pattern. However, there are some spots in my app where a form is specifically for that type of object (i.e.: the object is not nested, but is instead the root object used in the form).

Because fields is a required prop for withFieldGroup components, there doesn't seem to be a way to say "use the root object, not a nested property". Is this possible, or would this need to be a feature request?
