I have set a workflow on my board to prevent any issue to be moved to DONE if it has any of its subtasks not done.
I've tried to configure Screens but none of them refers to the subtasks.
I could set one generic and when trying to move to Done the issue with not the 100% of the subtasks completed, I get this message (which is not clarifying to the user what is missing)

Any clue of how to clarify what is missing to the user?
Thanks!
