Is it possible to have 'directed edges' instead of the symmetric one that the relation directive specifies?

type Person @model {
  id: ID! @isUnique
  firstName: String!
  surName: String!
  gender: String
  dateOfBirth: DateTime
  mother: Person @relation(name: "Mother")
  father: Person @relation(name: "Father")
  children: [Person!]! @relation(name: "Children")
}

That's not possible in Graphcool. We introduced unidirectional relations in Prisma, which I can recommend to take a look at 🙂

Thanks @nilan I'll take a look
