Auto-create "Incident" entity without Interview Entity Collection

Summary

Auto-create "Incident" entity without Interview Entity Collection

Content

Hi,

     We have built an OPA Interview and successfully integrated with Service Cloud. 

We have already setup entities in OPA rulebase like this. 

1. Global(Contact)
2. Financial Application Custom Object (child of Global)
3. Incident (child of Financial Application Custom Object)

OPA Interview will collect information for Global(Contact) and Financial Application Custom Object. But, I need to create an "Incident" automatically and default/hard-code with following values, without showing it in the OPA Interview. 

• Incident.Primary Contact = logged in contact
• Incident.Category = Financial Application

Also, there should be only one "Incident" instance..When OPA Interview resumes, it should not create another Incident.
