title: How can I append a list object in dynamodb with AWS Amplify and Graphql
body: <p>When I execute this mutation query (with review id 5) I expect that, when ID 5 is not in the array list, that this will be added to the dynamodb Reviews (type List). But instead the complete Reviews will be overwritten with this object</p>
  
  <p>How can I append or update specific values in de DynamoDB Reviews list array?</p>
  
  <pre><code>  mutation CreateUser{
      updateObject(input:{id:"d77d2ec2-b4a3-43b7-bb0e-9ef6f1e6fd76", reviews: [{
        id:5
        score: 8
        description: "Ramon11"
        email:"jan1111@jan.nl"
      }] })
      {
          id
          name
          reviews {
            id
          }
      }
  }
  
  **In my schema this code is there:** 
  type Object @model @searchable{
    id: ID!
    reviews: [Review]
    profile: Profile @connection
  }
  
  
  type Review{
    id: ID!
    score: Int!
    description: String!
    email: String!
  }
  </code></pre>
