CMMN Form Field

In a BPMN user task I’m able to define form fields, with types, constraints and properties. I can’t do that with a CMMN user task.
Is there a way to port that feature to CMMN user task. And for my curiosity a reason it’s not there?
I have a custom implementation of the task list that uses extensively the field definitions.

Are you automating your CMMN case? What is the usecase for having the form fields.

To simplify development. My cmmn UI is dynamically rendered. Most of my user tasks are simple with one or two input text, a Boolean. Having the form fields means I don’t need a form HTML for every tasks. This would make the development and update of the many cmmn much quicker.
