Retrieve an array of data from a multiline text field using jira smart values

[Priyanka K]

I do have Multiline textfield which contains JSON Data, I would like to get the data of a particular array which names as X. 

For Example

DataField(Multiline Text Field): 

{

     "AAAA" : "1234"

     "BBBB"  :  "23345"

     ------------

     ------------

    -----------

    "scopeData" : [          

              "908"

              "405"

              "302"

    ],

    -------------

   --------------

}

My Expected Output is to a label field name as

labelField, which contains data as 908, 405,302
