Alternative to Append export-csv powershell - powershell

Question

I add user logon and logout tracking script
I found that some computers do not export csv as they have powershell 2.0 because append is not supported is there any alternative?
$ErrorActionPreference = 'Continue'
####**** Tracking user logon *****#####
$username = $env:USERNAME
$computername = $env:COMPUTERNAME
$ipv4 = Test-Connection -ComputerName (hostname) -Count 1 | foreach { $_.ipv4address }
$ipv6 = Test-Connection -ComputerName (hostname) -Count 1 | foreach { $_.ipv6address }
$timeformat='MM-dd-yyyy hh:mm:ss tt'
$time = (Get-Date).ToString($timeformat)
$action = 'Logon'
$filedate = 'MM-dd-yyyy'
$filename = 'CompInfo' + ' ' + $(Get-Date).ToString($filedate)
#Creates custom table and sorts the information
$table= New-Object –TypeName PSObject -Property #{
'Date/Time' = $time
'Username' = $username
'ComputerName'= $computername
'IPv4 Address' = $ipv4
'IPv6 Address' = $ipv6
'Notes/Action' = $action
} | Select date/time, username, computername, 'IPv4 Address', 'IPv6 Address', notes/action
$table | Export-Csv "d:\$env:username.csv" -NoClobber -append -NoTypeInformation
