Master checkbox to select some but not all other checkboxes

[DLombard]

I have 5 categories, each with a number elements, and each element has a check box linked to a cell. Can I create a 5 master check boxes, each to link to all the elements in a given category? I have been able to figure out how to link the master to ALL checkboxes in the active sheet, but not to multiple but selective checkboxes. Grateful for any input! I am using ActiveX checkboxes, in case that is of importance.

A few examples for you
Important - Name is CheckBox\Properties\ Name

[COLOR=#ff0000][I]'array of category checkbox names[/I][/COLOR] - assign CheckBox11 value
Private Sub CheckBox11_Click()
    Dim obj As OLEObject, V As Variant, N As Variant
    V = CheckBox11.Object.Value
    For Each N In Array("CheckBox1", "CheckBox2", "CheckBox3", "CheckBox4", "CheckBox5")
        Me.OLEObjects(N).Object.Value = V
    Next N
End Sub

[I][COLOR=#ff0000]'common start to names[/COLOR][/I] - assign CheckBox12 value
Private Sub CheckBox12_Click()
    Dim obj As OLEObject, V As Variant
    V = CheckBox12.Object.Value
    For Each obj In Me.OLEObjects
        If TypeName(obj.Object) = "CheckBox" Then
            If Left(obj.Name, 4) = "catA" Then obj.Object.Value = V
        End If
    Next obj
End Sub

[I][COLOR=#ff0000]'common start to caption[/COLOR][/I] - assign CheckBox13 value
Private Sub CheckBox13_Click()
    Dim obj As OLEObject, V As Variant
    V = CheckBox13.Object.Value
    For Each obj In Me.OLEObjects
        If TypeName(obj.Object) = "CheckBox" Then
                If Left(obj.Object.Caption, 4) = "catB" Then obj.Object.Value = V
        End If
    Next obj
End Sub
