You can use Custom Elements for default values:

{
  "name": "Delegate Expression Task",
  "id": "com.camunda.example.DelegateExpressionTask",
  "appliesTo": [
    "bpmn:ServiceTask"
  ],
  "properties": [
    {
      "label": "Implementation",
      "type": "String",
      "value": "foo",
      "editable": true,
      "binding": {
        "type": "property",
        "name": "camunda:delegateExpression"
      }
    }
  ],
  "entriesVisible": {
    "_all": true
  }
}

If you want this template to be applied by default make sure to also set isDefault to true.

Does this help?
