How to trigger calls from task "type": "DYNAMIC" into http task

[serhii-piskunov]

Hello experts, I am stuck with dynamic task creation.

  "name": "SendEmail",
  "schemaVersion": 2,
  "version": 1,
  "failureWorkflow": "ErrorLogging",
  "tasks": [
    {
      "name": "simple_event",
      "taskReferenceName": "build_email_context",
      "inputParameters": {
        "taskToExecute": "${workflow.input.taskName}",
        "data": {
          "workflowId": "${workflow.workflowId}",
          "biId": "${workflow.input.id}",
          "_userContext": "${workflow.input._userContext}"
        }
      },
      "type": "DYNAMIC",
      "dynamicTaskNameParam": "taskToExecute"
    }
  ]
}```

Which should trigger dynamically call to the task which will do the call to the backend for generating email context
```{
  "name": "build_welcome_email_context",
  "taskReferenceName": "build_welcome_email_context",
  "inputParameters": {
    "data": {
      "workflowId": "${workflow.workflowId}",
      "biId": "${workflow.input.id}",
      "_userContext": "${workflow.input._userContext}"
    },
    "uri": "http://uri.com",
    "type": "io.type.email.context.fill",
    "connectTimeOut": 120000,
    "readTimeOut": 125000
  },
  "type": "HTTP",
  "startDelay": 0,
  "optional": false,
  "asyncComplete": false
}```
We have on our project 5 different emails and want to build for them context by passing the task names. The goal of having two steps in the workflow first to build context depends on the task name and second send an email depends on the task name too. I read this article https://conductor.netflix.com/documentation/configuration/workflowdef/operators/dynamic-task.html but there are only task definitions that trigger by the dynamic task depending on the shipping service value and do nothing.
Q: 
1. Is it possible to create a dynamic task that will call the task or another workflow and after finishing the workflow have the two steps in the completed workflow? Like this:

2.  Can I define task definition what can do this HTTP call or do I  need a task for it?
