Prisma

Is there any way to do a nested create mutation without referencing the id of the connected field?

i.e., instead of 
```
mutation updateAuthorAndConnectContactDetails {
  updateAuthor(
    id: "ciz7573ffx1w70112hwj04hqv"
    description: "I write posts"
    contactDetailsId: "ciz7573ffx1w80112cjwjduxn"
  ) {
    id
    contactDetails {
      email
    }
  }
}
```
i could do something like this:
```
mutation updateAuthorAndConnectContactDetails {
  updateAuthor(
    id: "ciz7573ffx1w70112hwj04hqv"
    description: "I write posts"
    contactDetails: {email: "nilan@graph.cool"}
  ) {
    id
    contactDetails {
      email
    }
  }
}
```

There's an open FR for that: <https://github.com/graphcool/graphcool/issues/257>
