How to Dynamically Add Sub Tasks/ Screens during Transition ?

[Asheesh]

Following is the scenario:

There's State in Workflow, "Review of Unit Test Case". If  defects are  identified during review, each with different Priorities and Details.

How to Capture these details during Transition, I see two options:

1. Automation

2. Create Screen for each defect. It can be multiple with same fields like , Priority, Details, Associate Files/ Code, Details, Due Date. Trigger this during transition.

One of the issues is it could be multiple. 

Please advise, the strategy / solution.

Thanks
