Can I run as different user via the Application Launcher?

Windows has this feature, per, enabled with

New-ItemProperty -Path "HKCU:\Software\Policies\Microsoft\Windows\CurrentVersion\Explorer" -Name ShowRunasDifferentuserinStart -Value 1 -PropertyType DWORD -Force

which uses RunAs, but although Linux obviously has sudo and su -c '', there doesn’t appear to be a GUI equivalent despite having multiple users on a system being as normal. Have I missed something?

Being able to configure something for a different user via my account, and being able to run CLI apps as the superuser via the Launcher would be darn useful.
