Hello! I am configuring a Board of my project to have more control of the status of Epics/Issues, but there is an element that I can't show correctly and that is the percentage of Done issues that are inside an epic. With the column "Progress" the only thing that is shown is what is registered in "Time registered", but nothing related to the percentage of Done issues of the Child issues of an Epic. I have tried with almost all the columns and nothing: neither Status, nor Work Ratio... nothing manages to show this percentage of the attached screenshot. The progress of this epic should be 30% (which is what I see when I enter the Epic page next to Child issues) and not 100% as shown on the Board. I'd need to be able to access from the Dashboard to the information about % of Done issues of an Epic. 
Can anyone help me? Thanks
