Hi,

Is it possible to append a value from a FillTask integration onto the end of a field? 

For example, a payload a bit like this:

{  
   "case_id": "{caseReference}", 
   "stage_name": "{stageName}",
   "data": {
      "textField": "{textField current value} and append something to the end of the text"
   },
   "ucrn": "{ucrn}",
   "published": "true",
   "submissionType":"new",
   "formCalculator": "true"  
}

I've got a field that's a log of previous interactions and would like to add data from an external system into it if it's possible. It's a repeated stage so putting the data into another field isn't an option. 

Thanks
