Creating a persistent format across several pages

Give this a try as a macro, just edit the "sheet3" references to the name of the template sheet you're going to keep hidden.

Sub NewSheet()
Dim NumSheets As Long
    Sheets("Sheet3").Visible = True
    NumSheets = ActiveWorkbook.Worksheets.Count
    Sheets("Sheet3").Copy After:=Sheets(NumSheets)
    Sheets("Sheet3").Visible = False
End Sub
