Create comment and move cursor to start of comments

Hi,
Hoping someone could help, I could not find the answer using the search function.

I have found code that adds a comment to a cell, and adds the text from that cell into the comment, with time and date. If a comment already exists for that cell it adds the text to the bottom of the comment.
Which is the question, how do I make it so each time I run the macro it adds the cell text to the top of the comment.


This is the code I have at the moment.

Sub CommentDateTimeAdd()
'adds Excel comments with date and time,
'  positions cursor at end of comment text


  Dim strDate As String
    Dim cmt As Comment
   
  strDate = "dd-mmm-yy hh:mm"

    Set cmt = ActiveCell.Comment
  
    If cmt Is Nothing Then
      Set cmt = ActiveCell.AddComment
      cmt.Text Text:=Format(Now, strDate) & Chr(10) & ActiveCell.Value & Chr(10)
  
    Else
        cmt.Text Text:=cmt.Text & Chr(10) _
        & Format(Now, strDate) & Chr(10) & ActiveCell.Value & Chr(10)
      End If
    
    With cmt.Shape.TextFrame
      .Characters.Font.Bold = False
    End With
   End Sub

Thanks in advance,
