AccessRestrictions AddIP for Multiple App Services in Azure Powershell - azure

Question

I have an Azure powershell script where the user has to add in the app service name, IP address and so on. I have 4 web apps where I would like to add the same IP address to. I would like to hard code the app service name so the user does not have to input it. How can I achieve this in powershell? Here is my code:
Param
(
# Name of the resource group that contains the App Service.
[Parameter(Mandatory=$true)]
$RGName,
# Name of your Web or API App.
[Parameter(Mandatory=$true)]
$WebAppName,
# priority value.
[Parameter(Mandatory=$true)]
$priority,
# WhitelistIp values.
[Parameter(Mandatory=$true)]
$IPList,
# rule to add.
[PSCustomObject]$rule
)
function Add-AzureIpRestrictionRule
{
$ApiVersions = Get-AzureRmResourceProvider -ProviderNamespace Microsoft.Web |
Select-Object -ExpandProperty ResourceTypes |
Where-Object ResourceTypeName -eq 'sites' |
Select-Object -ExpandProperty ApiVersions
$LatestApiVersion = $ApiVersions[0]
$WebAppConfig = Get-AzureRmResource -ResourceType 'Microsoft.Web/sites/config' -ResourceName $WebAppName -ResourceGroupName $RGName -ApiVersion $LatestApiVersion
$WebAppConfig.Properties.ipSecurityRestrictions = $WebAppConfig.Properties.ipSecurityRestrictions + #($rule) |
Group-Object name |
ForEach-Object { $_.Group | Select-Object -Last 1 }
Set-AzureRmResource -ResourceId $WebAppConfig.ResourceId -Properties $WebAppConfig.Properties -ApiVersion $LatestApiVersion -Force
}
$IPList= #($IPList-split ",")
Write-Host "IPList found "$IPList"."
$increment = 1
foreach ($element in $IPList)
{
if ($element -eq "" -OR $element -eq " ") {continue}
else
{
$element=$element.Trim()
$rule = [PSCustomObject]#{
ipAddress = "$($element)/32"
action = "Allow"
priority = "$priority"
name = "WhitelistIP"+ $increment}
$increment++
Add-AzureIpRestrictionRule -ResourceGroupName "$RGName" -AppServiceName "$WebAppName" -rule $rule
}
}
$OutboundIP = #(Get-AzureRmWebApp -Name "$WebAppName" -ResourceGroupName "$RGName").possibleOutboundIPAddresses -split ","
$increment = 1
foreach ($element in $OutboundIP)
{
$rule = [PSCustomObject]#{
ipAddress = "$($element)/32"
action = "Allow"
priority = "$priority"
name = "OutboundIP"+ $increment}
$increment++
Add-AzureIpRestrictionRule -ResourceGroupName "$RGName" -AppServiceName "$WebAppName" -rule $rule
}
so my $WebAppName i want it to be hard coded, but I have 4 of these web-apps, how do I get this script to run 4 times with just having the user input his IP address once, all variables stay the same, just the $WebAppName should change to the hard coded values i give

You could something like the following (If I've correctly understood the problem).
$webAppNames = 'a,b,c,d'
$webAppList = $webAppNames.split(',')
Foreach($webAppName in $webAppList) { ....do stuff }
