Code To Target 2 Cells G10 And N536

I require the following part of the code to target 2 cells G10 and N536

i guess this is simple but just not sure how it will work

Case Target.Address = "$G$10"
If Not IsDate(Target.Value) Then Exit Sub
Dim DateSuffix As String
Select Case Day(Target.Value)
Case 1, 21, 31
DateSuffix = "st"
Case 2, 22
DateSuffix = "nd"
Case 3, 23
DateSuffix = "rd"
Case 4 To 30
DateSuffix = "th"
End Select
Application.EnableEvents = False
Target.Value = Format(Target.Value, "d") & DateSuffix & Format(Target.Value, " mmmm, yyyy")
Application.EnableEvents = True

End Select
