Another way is to create a spreadsheet from a portlet which displays all the rights and their license requirement.
Then you can look at the rights of the user in the GUI where you see from they are coming from.
Typically instance and OBS rights do have lower license requirement than global, which allows you to tune the rights for lower license requirement.
Some rights like the administrative rights only exist as global. Then the option is to have a shared ID for doing work which require those rights and personal ID's for all other work.
Unless for reporting purposes you need nominations that give the auto rights you could replace eg the project manager with somebody else.
My recollection is that collaboration managers and participants are not displayed in license information portlets, though they do required licenses.
