Configure Visual Studio Code to run PowerShell for Windows and PowerShell Core Simultaneously

I have got Visual Studio Code 1.43.1 to successfully toggle between PowerShell Core V7 and Windows PowerShell 5.1 using the ShellLauncher.  PowerShell Core 7 doesn't seem to like it's predecessor, so removes the install directory.

"terminal.integrated.shell.windows": "C:/Program Files/PowerShell/7/pwsh.exe",    
    "shellLauncher.shells.windows": [{
        "shell": "C:/Program Files/PowerShell/7/pwsh.exe",
        "label": "PowerShell 7 Core"
    },
    {
        "shell": "C:/Windows/system32/WindowsPowerShell/v1.0/powershell.exe",
        "label": "Windows PowerShell 5.1"
    }
    ]

I can use the key mapping in the editor pane to switch the PowerShell version, displayed in the terminal window  drop down version selection  - you don't get the nice label ( see above)  and also you seem to get lots on instances if you repeatedly toggle:

Hope this helps somebody.
