Has anyone any examples of using Cubeview extender rules to change the logo displayed in a report based on the entity selected

I got a basic example working which used workflow assigned entities and read a text property on the first entity in order to pass the logo name into the filepath. I tested further and managed to get an example working which read the Cubeview POV entity and passed this into the logo filepath. I then saved a different logo for each entity. It seems to work, atleast well enough for me to tell the partner it should be feasible, without creating numerous versions of the same report. Here is the sample of that last example:
Case Is = CVExtenderFunctionType.FormatReportUIItem
Dim uiItem As CVExtenderReportUIItem = args.Report.CurrentUIItem

If uiItem.UIItemType = XFReportUIItemType.PageHeaderPictureBoxLogo Then
'-------------------------------
Dim objKeyedByDimTypeInt As KeyedByDimTypeList(Of CubeViewPOVMember) = args.CubeView.CubeViewPovMembers
Dim TextValue As String = objKeyedByDimTypeInt.Entity.Name
'----------------------------

uiItem.SetPictureBoxImage(FileSystemLocation.ApplicationDatabase,""Documents/Public/DashboardImages/"" & TextValue & "".png"",TriStateBool.TrueValue)
End If

Here is how I have done it. It actual put a different logo depending on the company.

Case Is = CVExtenderFunctionType.FormatReportUIItem
Dim uiItem As CVExtenderReportUIItem = args.Report.CurrentUIItem
uiitem.FontFamily = "Calibri"
uiitem.FontSize = 11

If uiItem.UIItemType = XFReportUIItemType.PageHeaderPictureBoxLogo Then

If args.CubeView.CubeViewPovMembers.Entity.Name.Contains("SV") Then

uiItem.SetPictureBoxImage(FileSystemLocation.ApplicationDatabase,"Documents/Public/tb_special vehicles_rgb.png", TriStateBool.TrueValue)
uiItem.Height = 30
uiItem.width = 150
