title: Is there a way to change how Mobilehub changes IAM authenticated Role?
body: <p>At the moment when you finish configuring a DynamoDB table the authenticades role creates this lines:</p>
  
  <pre><code>"Effect":"Allow",
      "Action":[
      "dynamodb:BatchWriteItem",
      "dynamodb:DeleteItem",
      "dynamodb:PutItem",
      "dynamodb:UpdateItem",
      "dynamodb:BatchGetItem",
      "dynamodb:DescribeTable",
      "dynamodb:GetItem",
      "dynamodb:ListTables",
      "dynamodb:Query",
      "dynamodb:Scan"
    ],
    "Resource": [
      table1
    ]
  </code></pre>
  
  <p>Per table but you can even put all tables in just 1 REsource, this is a waste of memory and dow im getting LimitExceeded error with only 10 tables.
  My question is: Is there a way of configuring how MobileHub creates this roles or a way of handling this LimitExceeded error?</p>
