VBA - Copy and paste from excel to PPT for multiple worksheets with different ranges

[jbench18]

Hey everyone, looking for some help with updating the code below. The code works fine in regards to copying specific ranges on multiple worksheets and exporting it to an existing powerpoint template. The problem I have now is each range i.e. rng_1, rng_2 are different sizes so it requires some manual updating to make sure the slides are readable and centered. Is there a way to autofit the range within the spreadsheet? Is a better solution to call out where the range should be pasted for each cell? What's the most efficient way to do that?

Thanks in advance for any help

Sub excelrangetopowerpoint_month()
    Dim powerpointapp As Object
    Set powerpointapp = CreateObject("powerpoint.application")

    Dim destinationPPT As String
    destinationPPT = ("Location for File")

    On Error GoTo ERR_PPOPEN
    Dim mypresentation As Object
    Set mypresentation = powerpointapp.Presentations.Open(destinationPPT)
    On Error GoTo 0

    Application.ScreenUpdating = False

    PasteToSlide mypresentation.Slides(5), Worksheets("Account Summary").Range("rng_1")
    PasteToSlide mypresentation.Slides(4), Worksheets("Account Overview").Range("rng_13")
    PasteToSlide mypresentation.Slides(8), Worksheets("Success Metrics").Range("rng_2")
    PasteToSlide mypresentation.Slides(6), Worksheets("Financial - Pan ").Range("rng_3")
    PasteToSlide mypresentation.Slides(11), Worksheets("Financial - C").Range("rng_4")
    PasteToSlide mypresentation.Slides(14), Worksheets("Financial - M").Range("rng_6")
    PasteToSlide mypresentation.Slides(17), Worksheets("Financial - N").Range("rng_5")
    PasteToSlide mypresentation.Slides(7), Worksheets("Contract - Pan ").Range("rng_7")
    PasteToSlide mypresentation.Slides(12), Worksheets("Contract - C").Range("rng_8")
    PasteToSlide mypresentation.Slides(18), Worksheets("Contract - N").Range("rng_9")
    PasteToSlide mypresentation.Slides(15), Worksheets("Contract - M").Range("rng_10")
    PasteToSlide mypresentation.Slides(9), Worksheets("Stakeholder Summary").Range("rng_11")
    PasteToSlide mypresentation.Slides(10), Worksheets("Program Tracker").Range("rng_12")
    
    'duplicate this line for all slides/ranges
    'PasteToSlide mypresentation.Slides(2), Worksheets("objectives").Range("m2")

    powerpointapp.Visible = True
    powerpointapp.Activate

    Application.CutCopyMode = False

ERR_PPOPEN:
    Application.ScreenUpdating = True 'don't forget to turn it on!
    If Err.Number <> 0 Then
        MsgBox "Failed to open " & destinationPPT, vbCritical
    End If
End Sub


Private Sub PasteToSlide(mySlide As Object, rng As Range)
    rng.Copy
    mySlide.Shapes.PasteSpecial DataType:=2 '2 = enhanced metafile

    Dim myShape As Object
    Set myShape = mySlide.Shapes(mySlide.Shapes.Count)

    myShape.Left = 278
    myShape.Top = 175
End Sub
