Powershell Checkbox that selects other checkboxes

I have a basic form UI in powershell. I have a series of 3 individual checkboxes with the following code:

    $CBlabel = New-Object System.Windows.Forms.Label
    $CBlabel .Location = New-Object System.Drawing.Point(10,125)
    $CBlabel .Size = New-Object System.Drawing.Size(280,20)
    $CBlabel .Text = "Select a box:"
    $form.Controls.Add($CBlabel )

    $cb1Checkbox = New-Object System.Windows.Forms.Checkbox
    $cb1Checkbox .Location = New-Object System.Drawing.Size(10,145)
    $cb1Checkbox .Size = New-Object System.Drawing.Size(280,20)
    $cb1Checkbox .Text = "Checkbox 1"
    $form.Controls.Add($cb1Checkbox )

    $cb2Checkbox = New-Object System.Windows.Forms.Checkbox
    $cb2Checkbox .Location = New-Object System.Drawing.Size(10,165)
    $cb2Checkbox .Size = New-Object System.Drawing.Size(280,20)
    $cb2Checkbox .Text = "Checkbox 2"
    $form.Controls.Add($cb2Checkbox )

    $cb3Checkbox = New-Object System.Windows.Forms.Checkbox
    $cb3Checkbox .Location = New-Object System.Drawing.Size(10,185)
    $cb3Checkbox .Size = New-Object System.Drawing.Size(280,20)
    $cb3Checkbox .Text = "Checkbox 3"
    $form.Controls.Add($cb3Checkbox )

I would like to add a 4th checkbox below this that says "Select All" and have it be dynamic if possible. If I select it, it automatically selects checkboxes 1, 2, and 3. If I unselect checkbox 2 (or any other checkbox), it automatically unselects the "Select All" checkbox. Is this possible?
