Emailing multiple ranges as attachments from VB code

Question

I have used some standard code from the internet to use a button to create an email in Outlook with an attachment that is a range in the worksheet where the button is pressed.The code works beautifully. How can I extend the code to attach two or more ranges? In the code below, I already started initializing a second Source and Dest, but then lost confidence regarding how this should be applied.

Private Sub CommandButton2_Click()

    Dim Source As Range
    Dim Source2 As Range
    Dim Dest As Workbook
    Dim Dest2 As Workbook
    Dim wb As Workbook
    Dim TempFilePath As String
    Dim TempFileName As String
    Dim FileExtStr As String
    Dim AutoPrint As String
    Dim FileFormatNum As Long
    Dim OutApp As Object
    Dim OutMail As Object

    Set Source = Nothing
    Set Source2 = Nothing
    On Error Resume Next
    Set Source = Range("A1:M47").SpecialCells(xlCellTypeVisible)
    Set Source2 = Range("AB1:AN47").SpecialCells(xlCellTypeVisible)
    On Error GoTo 0

    If Source Is Nothing Then
        MsgBox "The source is not a range or the sheet is protected, please correct and try again.", vbOKOnly
        Exit Sub
    End If

    With Application
        .ScreenUpdating = False
        .EnableEvents = False
    End With

    Set wb = ActiveWorkbook
    Set Dest = Workbooks.Add(xlWBATWorksheet)
    Set Dest2 = Workbooks.Add(xlWBATWorksheet)

    Source.Copy
    With Dest.Sheets(1)
        .Cells(1).PasteSpecial Paste:=8
        .Cells(1).PasteSpecial Paste:=xlPasteValues
        .Cells(1).PasteSpecial Paste:=xlPasteFormats
        .Cells(1).Select
        Application.CutCopyMode = False
    End With
    
    If Range("AC6") <> "" Then
    Source2.Copy
    With Dest2.Sheets(1)
        .Cells(1).PasteSpecial Paste:=8
        .Cells(1).PasteSpecial Paste:=xlPasteValues
        .Cells(1).PasteSpecial Paste:=xlPasteFormats
        .Cells(1).Select
        Application.CutCopyMode = False
    End With
    End If

    TempFilePath = Environ$("temp") & "\"
    TempFileName = "Selection of " & wb.Name & " " & Format(Now, "dd-mmm-yy h-mm-ss")

    If Val(Application.Version) < 12 Then
        'You use Excel 97-2003
        FileExtStr = ".xls": FileFormatNum = -4143
    Else
        'You use Excel 2007-2016
        FileExtStr = ".xlsx": FileFormatNum = 51
    End If

    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)
    AutoPrint = Range("Y6").Value

    With Dest
        .SaveAs TempFilePath & TempFileName & FileExtStr, FileFormat:=FileFormatNum
        On Error Resume Next
        With OutMail
            .to = Range("S6").Value
            .CC = Range("S3").Value
            If Range("T3").Value = "Enter bcc addresses manually here" Then
            .bcc = ""
            Else
            .bcc = Range("T3").Value
            End If
            .Subject = Range("V6").Value
            .Body = Range("U6").Value
            .Attachments.Add Dest.FullName
            'You can add other files also like this
            '.Attachments.Add ("C:\test.txt")
            If AutoPrint = "Yes" Then
            .Send   'or use .Display
            Else
            .Display
            End If
        End With
        On Error GoTo 0
        .Close savechanges:=False
    End With

    Kill TempFilePath & TempFileName & FileExtStr

    Set OutMail = Nothing
    Set OutApp = Nothing

    With Application
        .ScreenUpdating = True
        .EnableEvents = True
    End With

End Sub
