I would highly recommend posting this feedback or upvoting if it exists already in the Idea Exchange. I know there is work underway to update the Admin UI and these type of detailed comments are valuable to the Product team.

As an alternative to some of these scenarios I have seen many clients make good use of the Administration API to manage across many report suites.

>>>

Adobe's Administration API lets you change report suite and user settings without the need to use Admin Tools. This feature is useful if you have a custom reporting interface, letting you make changes to the report suite without having to log in to the interface. There are no limitations to using this API, as compared to Admin Tools. Meaning, if a certain action can be done within Admin Tools, that same action can be done using the Administration API.

Best,
