title: Overide entire relation field with Prisma?
body: <p>With Prisma is it possible to completely overwrite a relation rather than connecting and disconnecting individual nodes? </p>
  
  <p>Say I have a user with a groups relation to groups 1 and 2: </p>
  
  <pre><code>user: {
      id: "abcd"
      groups: [
          {id: 1},
          {id: 2}
      ]
  }
  </code></pre>
  
  <p>If I want to make this user only connected to group 3:</p>
  
  <pre><code>user: {
      id: "abcd"
      groups: [
          {id: 3}
      ]
  }
  </code></pre>
  
  <p>Do I have to do this?: </p>
  
  <pre><code>mutation {
    updateUser(
      where: { id: "abcd" }
      data: {
          groups: {
              disconnect: {
                  id: "1"
                  id: "2"
              }
              connect: {
                  id: "3"
              }
          }
      }
    ) {
      id
    }
  }
  </code></pre>
  
  <p>Or is there some way of overwriting the entire relation:</p>
  
  <pre><code>mutation {
    updateUser(
      where: { id: "abcd" }
      data: {
          groups: [{id:3}]
      }
    ) {
      id
      name
    }
  }
  </code></pre>
