[RESOLVED] Left justified ControlButton caption

Excel question. Following code creates a CommandBar and several ControlButtons arranged vertically. Is there any way to make the ControlButton captions left justfied like in menus? I've played around adding spaces, Left$, Right$, and nothing seems to work. The captions are always centered within the width of the ControlButton. Ideas?

VB Code:

Sub DisplayToolBar()
    'CommandBar caption is left justified
    Dim cbar As CommandBar, cbctl As CommandBarButton, i As Integer
    On Error Resume Next
    Application.CommandBars("Custom Toolbar").Delete
    Set cbar = Application.CommandBars.Add(Name:="Custom Toolbar", _
        Position:=msoBarFloating, MenuBar:=False, Temporary:=True)
    For i = 1 To 5
        With cbar.Controls.Add(Type:=msoControlButton)
            .Style = msoButtonCaption
            'ControlButton captions are centered.  How to make left/right justified????
            .Caption = "test" & i & Left$("xyadafdadsfadf", i)
            .OnAction = "Action"
            .BeginGroup = True
            .Width = 200
        End With
    Next i
    With cbar
        .Width = 200
        .Enabled = True
        .Protection = msoBarNoCustomize
        .Visible = True
    End With
End Sub

Edit: played around with spaces and Left$ enough to figure it out
