How can I format this output better? - powershell

Question

I would like to pipe the output to a .csv, but when I do, I cannot add the host name, so I have settled on shooting it to a .txt, however, I don't have much latitude to manipulate the results.
The original one-liner was:
$([ADSI]"WinNT://$env:COMPUTERNAME").Children | where {$_.SchemaClassName -eq 'user'} | select #{l='name';e={$_.name}},#{l='LastLogin';e={$_.lastlogin}} | export-csv C:\csv.csv
I have modified it to run against a list, however, the original code does not denote the host name... I would love to know how to do this. Here is the modified code:
$computers = Get-Content C:\LocalLogin.txt
ForEach ($Computer in $Computers)
{
$COMPUTER | Out-File C:\StaleLocalLogins.txt -Append
$([ADSI]"WinNT://$COMPUTER").Children |
where {$_.SchemaClassName -eq 'user'} |
select #{l='name';e={$_.name}},#{l='LastLogin';e={$_.lastlogin}} |
Out-File C:\StaleLocalLogins.txt -Append
}

So basically you can add the hostname from $env:COMPUTERNAME to a later part of the script. Below is a 1 liner but spaced for ease of reading
$([ADSI]"WinNT://$env:COMPUTERNAME").Children |
where {$_.SchemaClassName -eq 'user'} |
select #{l='name';e={$_.name}},#{l='LastLogin';e={$_.lastlogin}} |
%{
$_ |
Add-Member -MemberType NoteProperty -Name "HostName" -Value "$env:COMPUTERNAME"
$_ | Select-Object "HostName", "Name", "LastLogin"
} | Export-Csv "C:\Test\test.csv"
This part adds a new property to the PSCustomObject that was created. It stores the hostname. Then it reorders the customobject in the order HostName, Name, LastLogin
%{
$_ | Add-Member -MemberType NoteProperty -Name "HostName" -Value "$env:COMPUTERNAME"
$_ | Select-Object "HostName", "Name", "LastLogin"
}
here it is as a one-liner
$([ADSI]"WinNT://$env:COMPUTERNAME").Children | where {$_.SchemaClassName -eq 'user'} | select #{l='name';e={$_.name}},#{l='LastLogin';e={$_.lastlogin}} | foreach-object {$_ | Add-Member -MemberType NoteProperty -Name "HostName" -Value "$env:COMPUTERNAME"; $_ | Select-Object "HostName", "Name", "LastLogin"} | Export-Csv "C:\scripts\test.csv" -NoTypeInformation
