default email signature

I am creating an email from within Excel

With CreateObject("Outlook.Application").CreateItem(0)
                    .To = Sheets("Data").Range("B122").Value
                    .Subject = title
                    .Body = "Please confirm the outcome for" & Chr(13) & _
                    Chr(13) & _
                    "Surname - " & Sheets("Data").Range("B4").Value & Chr(13) & _
                    "Forenames - " & Sheets("Data").Range("B124").Value & Chr(13) & _
                    "Date of Birth - " & Sheets("Data").Range("B10").Value & Chr(13) & _
                     .Display

Is there any property I can use to tell Outlook to use the default email signature when Displaying the new email? I know the user can easily add the signature to the bottom of the mail before sending but it would be easier for them if the default was applied.

Thanks
