Creating complex JSON request in SOAP UI

Hi all

It's possible to create complex json request in SOAP UI?

For example like this:

{
"param1":{
"param1-1": "value1",
"param1-2": "value2",
"param1-3": "value3"
},
"param2":{
"param2-1": "value1",
"param1-2": "value4",
"param2-3": "value2"
},
"param3": [
    {
      "param3-1": "value1",
      "param2-3": "value3",
      "param3-2": [
        {
          "param3-2-1": "value",
          "param1-2": "value3"
        }
      ]
    }
  ]
}
