I want to add some observability and ability to predict the deadlines to my projects.
Teams use Kanban boards and use "Log Work" (time) to log work, and they write down "Remaining time" whenever they log work.
The questions are:
1) how do I display readonly text field on Epic, such that it is equal to sum of all "Original Estimate" of issues that belong to this epic?
2) and, how do I display readonly text field on Epic, such that it is equal to sum of all "Logged time" of all issues that belong to this epic?
