Let’s say I have my report of leads with 3 columns:
- onboarding status
- marketing status
- sales status
I would like to be able to create 3 pies for each status without having to create 3 separate reports.
I would also like to display this data in different ways: pie, table, etc, without having to create a report for each view.
I just ran into this same issue!! We had to add a new exclusion list and it means I have to go update 10+ reports instead of the 3 base reports 
what I’ll be doing now is building everything as a list/segment and then the reports will be based on segment membership so I only have to update my segments. A dumb workaround but should work.
