Modelling a QuestionnaireResponse that hasn't been started

Is there any way to indicate a QuestionnaireResponse has not been started?

At the moment, I’m just using ‘in-progress’, but I’d like to be able to distinguish between an empty response that has been created by the backend, and a response that has been started by a user.

Thanks!

Why would you have a QuestionnaireResponse instance if it hasn’t started? If you’re wanting to request that one be completed, that’s generally done using Task, not an incomplete QuestionnaireResponse.
