Possible to specify FQDN for new node address via iControl and Powershell?

Based on the answer posted by R Marc, I've created a function in PowerShell that creates pools with new FQDN nodes.

Function Create-Pools
{
    <
    .SYNOPSIS
    Creates a new pool with a new FQDN node
    >
    [CmdletBinding(HelpURI="https://devcentral.f5.com/questions/possible-to-specify-fqdn-for-new-node-address-via-icontrol-and-powershell")]
    param([Parameter(Mandatory=$true)][string]$poolName,
          [Parameter(Mandatory=$true)][string]$NodeFqdn,
          [Parameter(Mandatory=$true)][string]$port,
          [Parameter(Mandatory=$true)][System.Net.WebClient]$webclient,
          [Parameter(Mandatory=$true)][string]$F5Host)

    $webclient.headers.Add("Content-Type: application/json") 

    $json='{
        "members": [
            {
                "fqdn": {
                    "autopopulate": "enabled",
                    "tmName": "'+$NodeFqdn+'"
                },
                "name": "'+$NodeFqdn+':'+$port+'",
                "priorityGroup": 0
            }
        ],
        "name": "'+$poolName+'"
    }'
    $webclient.UploadString("https://$F5Host/mgmt/tm/ltm/pool","POST",$json)
}

Here's some sample usage:

 Construct the webclient object
$webclient = New-Object System.Net.WebClient
$creds = New-Object System.Net.NetworkCredential($username,$password)
$webclient.Credentials = $creds
Create-Pools -poolName "MyPoolName" -NodeFqdn "webserver.test.com" -port 80 -webclient $webclient -F5Host "MyF5Server"
