Analyzing a Board from the resume/synthesis of all tasks (not just by group)

Today we can analyze group by group in one board for information like the sum of all expenses from the same group or other columns with “group by,” or also the first and last date from the board considering the dates of all tasks. But I wish there was a way that I could get this type of information considering all tasks from all project board, having a full picture of things like total expenses or total range dates. I’ve tried to exemplify my suggestion with two pictures.
