How to center labels in a flowlayout panel in a Powershell / Winform GUI

In my Powershell GUI, I have in the middle, a tablelayout panel. This TableLayoutPanel have three columns. In the last column, I have a FlowLayout Panel.

In this FlowLayout panel I need to add, a random number of labels which depends of what is read in a external xml file. So If my xml have three labels, I need to add three labels.

I'm trying to align theses labels in the middle of the flowlayout panel with a left alignement, like that :

----------------------------
|                          |
|         -Label1          |
|         -Label2          |
|         -Label3          |
|                          |
----------------------------

But, it's not working, I could have a left alignement, but I don't success in the middle alignement. I have try with "middlecenter", but it's breaking left alignement.

FlowLayout Panel

$HashForAll.PanelLabel=New-Object System.Windows.Forms.FlowLayoutPanel
$HashForAll.PanelLabel.FlowDirection = "TopDown"
$HashForAll.PanelLabel.WrapContents = $false
$HashForAll.PanelLabel.BackColor = [string]$PanelLabelCfg.BackColor
$HashForAll.PanelLabel.Name ="PanelLabel"
$HashForAll.PanelLabel.BorderStyle =[string]$PanelLabelCfg.BorderStyle
$HashForAll.PanelLabel.Dock = "Fill"
$HashForAll.MiddleLayout.Controls.Add($HashForAll.PanelLabel,2,0)

And the labels

$sourceXML = [xml](Get-Content $ProductPath\Xml\ConnectionLabels.xml)
$etapes = $sourceXML.Dialer.Etapes.Etape
$i =1
foreach ($e in $etapes)
{
    $HashForAll.Lbl = New-Object System.Windows.Forms.Label
    $HashForAll.Lbl.AutoSize =$true
    $HashForAll.Lbl.Name = "Label"+$i
    $HashForAll.Lbl.TextAlign = "MiddleLeft"
    $HashForAll.Lbl.Font = New-Object System.Drawing.Font([string]$lblCfg.Font,[int32]$lblCfg.Size,[System.Drawing.FontStyle]::[string]$lblCfg.Style)
    $HashForAll.Lbl.ForeColor = [string]$lblCfg.Color
    $HashForAll.Lbl.Text = $e.Label
    $HashForAll.PanelLabel.Controls.Add($HashForAll.Lbl)
    $i++
}
