How can I make when a person enters a report are hidden / display fields depending on which report is?

Hello everyone, I have like 7 reports, and in every report so i want to show/hide the fields when the boss enters to edit the report depending what fields i show in the report.

something like: 

I'm the boss, so I have permission to see all reports, and if i go to the report 1 the fields that have to show will be "field1", "field2" and if the boss go to the report 2 the fields that have to show will be "field3", "field4". so "field1" and "field2" will hide

how can i do this?
