How to add a tag to a tag group in actions

Follow

Is it possible to add a tag to a tag group on user action over a notification. Right now it only allows an array of string of tags. I need to add a tag to a tag group, something like this. 

"push": {
"audience": {"tag": "surveyIncomplete", "group": "survey-status"},
"notification": { "alert": "You have an incomplete survey",
"actions": {"add_tag" : [{"survey-status": [ "surveyIncompleteNotified"]}]
}
},
"device_types": [ "android" ]
}
