Powershell - combining multiple for each into a single output - powershell

Question

Good morning everyone,
I am still learning powershell and have a script that my company run's. I have adjusted it slightly and it works well. however...
Overview
Script pulls in a CSV file and then for each device on the CSV it logs in and grabs all of the VIP information and then outputs it to a CSV that is dated and titled with the device name.
Ask
I would like adjust the script so that instead of having 50+ CSV files I could have a single CSV file with an extra column that would like the device name that all the VIPS are on. How do I do that?
Current Script
$user = "user"
$pass1 = Read-Host "Enter Netscaler Password"
$Devicelist = Import-Csv'C:\Users\user\Documents\20221110\20221109_Citrix_inventory_Master1.csv'
foreach ($device in ($Devicelist | ? { $_.fqdn -match "nsr" -and $_.State -match "Primary" -and $_.Configuration_viewable_with_Techops_login -match "Yes" })) {
Write-Host "Attempting to connect to $($device.fqdn)"
$SecurePassword = ConvertTo-SecureString $pass1 -AsPlainText -Force
$Credential = New-Object System.Management.Automation.PSCredential ($user, $SecurePassword)
$session = Connect-NetScaler -Hostname $device."IP address" -Credential $Credential -PassThru
$nsVIPs = Get-NSLBVirtualServer | select name, ipv46, port, curstate
$nsVIPs | Out-File C:\Users\user\Documents\20221110\VIPS\$(get-date -f yyyyMMdd)"_"$($device.fqdn)-"vips.csv"
}
Current CSV Input File format
Current output file format
What I would like to out file format to be

What have I tried

At the moment nothing except for research, I am guessing that I will need to hold of of the info in an array and then output it at the end. I just don't have a clue how to do that.
Thanks for looking and helping

You can change the code to first collect all data in one single variable $result and after the loop write all that out in a single CSV file.
To write csv, you need to use Export-Csv, not Out-File, which is intended to write simple text, not objects.
$user = "user"
$pass1 = Read-Host "Enter Netscaler Password"
$SecurePassword = ConvertTo-SecureString $pass1 -AsPlainText -Force
$Credential = New-Object System.Management.Automation.PSCredential ($user, $SecurePassword)
$today = '{0:yyyyMMdd}' -f (Get-Date)
$Devicelist = Import-Csv -Path 'C:\Users\user\Documents\20221110\20221109_Citrix_inventory_Master1.csv' |
Where-Object { $_.fqdn -match "nsr" -and
$_.State -match "Primary" -and
$_.Configuration_viewable_with_Techops_login -match "Yes" }
$result = foreach ($device in $Devicelist) {
Write-Host "Attempting to connect to $($device.fqdn)"
$session = Connect-NetScaler -Hostname $device.'IP address' -Credential $Credential -PassThru
Get-NSLBVirtualServer |
Select-Object name, ipv46, port, curstate, #{Name = 'Device Name'; Expression = {$device.fqdn}}
}
# now write out the csv file just once
$result | Export-Csv -Path "C:\Users\user\Documents\20221110\VIPS\$($today)_vips.csv" -NoTypeInformation
