Hi @PieterS - yes, it’s possible. You would need to build your template and code to accept all of the features a User Task would have. I think you need to build this all manually, however, as User Tasks are a separate item from Connectors, so there isn’t a template you can fork.
Depending on why you want to do this, you could also create a job worker that listens for User Tasks. That way the BPMN element is still a User Task, but your code is working with it. There are many examples if you search the forums, here is one such thread.
