不打开工作薄情况下合并该工作薄数据能否指定当前打开的工作薄（非打开的第1个表）

tntg534462

vba 代码：

Option Explicit
Sub 合并C62()
Dim MyPath, MyName, AWbName, FolderPath, FolderName
Dim Wb As Workbook, WbN As String
Dim G As Long
Dim Num As Long
Dim BOX As String
Application.ScreenUpdating = False
MyPath = ActiveWorkbook.Path
FolderPath = MyPath
FolderName = Dir(FolderPath & "\" & "C62*.CSV")
AWbName = ActiveWorkbook.Name
Num = 0
Do While FolderName <> ""
If FolderName <> AWbName Then
Set Wb = Workbooks.Open(FolderPath & "\" & FolderName)
Num = Num + 1
With Workbooks(1).ActiveSheet
.Cells(.Range("a1048576").End(xlUp).Row + 0, 43) = Left(FolderName, Len(FolderName) - 4)
For G = 1 To Sheets.Count
Wb.Sheets(G).UsedRange.Copy .Cells(.Range("a1048576").End(xlUp).Row + 1, 43)
Next
WbN = WbN & Chr(13) & Wb.Name
Wb.Close False
End With
End If
FolderName = Dir
Loop
Range("a1").Select
Application.ScreenUpdating = True
MsgBox "共合并了" & Num & "个工作薄下的全部工作表。如下：" & Chr(13) & WbN, vbInformation, "提示"
End Sub

以上是我百度论坛大佬给到的代码，问题：只会把数据合并导入到打开的工作薄第一个表，而我希望贴到的是我当前打开着的工作薄当前sheet

请问一下大神该如何修改呀
