I'd like to be able to create an Element Template for a User Task that automatically has formFields added in when selected. An example of possible syntax:
"properties": [{
"label": "Formfield 1",
"type": "String",
"value": "[predefined value for the formfield]",
"editable": true,
"binding":

{ "type": "camunda:formField", "name": "formFieldId" }

,
"constraints":

{ "notEmpty": true }

}]
