Macro pasting start row 4 not 1, headers, and sum total - excel

Question

I have this great macro that creates my sheet and copies and paste information starting in "A1" but I need it to paste starting in "A4" of the new sheet. I plan to add headings in row 1 and totals in row 3. So if you could point me in the right direction to figure that out too it would be great. The amount of rows will vary for the totals.
Sub CopyRangeFromMultiWorksheets()
Dim sh As Worksheet
Dim DestSh As Worksheet
Dim Last As Long
Dim CopyRng As Range
With Application
.ScreenUpdating = False
.EnableEvents = False
End With
'Delete the sheet "SUMMARY" if it exist
Application.DisplayAlerts = False
On Error Resume Next
ActiveWorkbook.Worksheets("SUMMARY").Delete
On Error GoTo 0
Application.DisplayAlerts = True
'Add a worksheet with the name "SUMMARY"
Set DestSh = ActiveWorkbook.Worksheets.Add
DestSh.Name = "SUMMARY"
'Move the worksheet "SUMMARY"
Sheets("SUMMARY").Select
Sheets("SUMMARY").Move Before:=Sheets(7)
'loop through all worksheets and copy the data to the DestSh
For Each sh In ActiveWorkbook.Worksheets
If IsError(Application.Match(sh.Name, _
Array(DestSh.Name, "EnGarde Data", "Service Data", "Usage", "TECHNICIAN", "MASTER", "Dropdown lists"), 0)) Then
'Find the last row with data on the DestSh
Last = LastRow(DestSh)
'Fill in the range that you want to copy
Set CopyRng = sh.Range("F2")
'Test if there enough rows in the DestSh to copy all the data
If Last + CopyRng.Rows.Count > DestSh.Rows.Count Then
MsgBox "There are not enough rows in the Destsh"
GoTo ExitTheSub
End If
'Copy range to new sheet
CopyRng.Copy DestSh.cells(Last + 1, "B")
'Copy the sheet name in the A column
DestSh.cells(Last + 1, "A").Resize(CopyRng.Rows.Count).Value = sh.Name
'Fill in the range that you want to copy
Set CopyRng = sh.Range("B6")
'Copy range to new sheet
CopyRng.Copy DestSh.cells(Last + 1, "C")
'Fill in the range that you want to copy
Set CopyRng = sh.Range("B4")
'Copy range to new sheet
CopyRng.Copy DestSh.cells(Last + 1, "D")
End If
Next
ExitTheSub:
Application.GoTo DestSh.cells(1)
'AutoFit the column width in the DestSh sheet
DestSh.Columns.AutoFit
With Application
.ScreenUpdating = True
.EnableEvents = True
End With
End Sub

Answer 1

When your macro completed, and all info pasted starting from "A1", you can simply insert the rows before first one. So add this line after ExitTheSub: as many times as as you want blank lines:
DestSh.Rows(1).Insert Shift:=xlDown
