Ribbonbar System Button

Hope someone has a solution for this because I am going mad :)

I have added a System Button and a CXTPRibbonControlSystemPopupBarListCaption to my ribbon bar like this:


Dim rbarGeneral As XtremeCommandBars.RibbonBar
Dim rbarPopup As XtremeCommandBars.CommandBarPopup

Set rbarGeneral = cbarGeneral.AddRibbonBar("Standard")

With rbarGeneral
        .EnableDocking xtpFlagStretched
        .EnableFrameTheme
End With

Set rbarPopup = rbarGeneral.AddSystemButton()
        rbarPopup.Id = ID_OTHER_SYSTEMBUTTON
        rbarPopup.Caption = "&Filer"

With rbarPopup.CommandBar
       Set rbarControl = cbarGeneral.CreateCommandBarControl("CXTPRibbonControlSystemPopupBarListCaption")
            rbarControl.Caption = "Seneste regnskaber"
            rbarControl.BeginGroup = True
            .Controls.AddControl rbarControl
End With


This works perfectly .. But I then want to create a MRU in this SystemPopupBarList .. The only problem is that I do not know how to reference that group in code at a later time (it is easy to add the MRU entries if I do it right after creating the SystemPopupBarList .. However I would like to do the same whenever a file is opened or saved as well.

So how do I reference that menu in code each time a file is loaded or saved so that I can add a new entry to it?
