How to use the JSON tool plugin incase the JSON URL will return multiple rows of JSON data

i have successfuly used the JSON tool plugin in webs service that returns single row such as :-
{
"activityId": "1079_563_crm_process1_approve_proposal",
"assignment": "admin",
"nextActivityId": "1093_563_crm_process1_send_proposal",
"processId": "563_crm_process1",
"status": "completed"
}
but now i need to call web services that return multiple rows of json data, but how i should configure the JSON tool plugin in-case the return JSON will have multiple rows , such as :-

{
"total":2,
"desc":false,
"sort":"name",
"start":0,
"data":
[

,

]
}
Is there a way for example to define a loop inside the JSOn tool plugin or something similar to?
