I'm unaware of a Prodigy interface that offers this functionality out of the box. So it sounds like you might be interested in designing a custom interface for your specific task. Given the high level of interaction you require, especially with the editable summary, this could be a lot of work.
So while the custom interface could be a valid option, I wonder if it's possible to simplify your interface instead. It sounds like one part of the problem is selecting sentences, which is something that a choice interface can do. Can you share anything about the final goal of the dataset? Is there a reason why the labels in the rightmost column are required?
