1 user- 4 id 's

Hi, i would like to ask if there is any way that will permit us to do the following:

we have one account manager that manage 4 different countries with different id so to keep control of them.

We do not want to log in from 4 different profiles.Is there any way to keep it simple for him so to have access directly to all his 4 id’s?

I don’t quite understand why the 4 logins in the first place.

You’re probably just looking for a way to separate data into security teams, like this
