Aha Develop - Ability to configure the Cards within the Sprints Merged

Enable the ability to configure the feature or requirements cards within the planned sprints.

Currently can only see the Reference ID, Name, "assigned to" picture (if entered), status and Estimate.

Would like to replace "assigned to" picture with user name, and show the Remaining time not the Overall Estimate.

Ideally ability to add to card any native or custom field.
