adapt and change code already posted to copy and split sheets

[rjmdc]

this was a code i adapted form the forum. it works
but its not quite what i need and i dont know how to tweak on my own. iv'e tried and just made a royal mess of things.
1- i need this code to update when re-run, look if there are sheets, create if not and if yes, Overwrite all data
2- i need also label sheet 1 as "All Payments" instead of workbook name which is the split name?
3- also keep all formatting from original workbook
is there anyone that can help me?

Sub Splitbook()

Dim xPath As String
xPath = "M:\all\FI Payments\Single Participant Payment Worksheets\split file 3\"
Application.ScreenUpdating = False
Application.DisplayAlerts = False
For Each xWs In ThisWorkbook.Sheets
   Select Case xWs.Name
      Case "All Payments"
      Case Else
    xWs.Copy
         Application.ActiveWorkbook.SaveAs Filename:=xPath & "\" & xWs.Name & ".xlsx"
         Application.ActiveWorkbook.Close False
   End Select
Next
Application.DisplayAlerts = True
Application.ScreenUpdating = True

MsgBox "Complete"
End Sub

i actually put this sub as part of a combination, also taken from the forum. sub splitbook is the part i need to uipdate but i am putting entire code in.

Sub parse_data()
    Dim lr As Long
    Dim ws As Worksheet
    Dim vcol, i As Integer
    Dim icol As Long
    Dim myarr As Variant
    Dim title As String
    Dim titlerow As Integer

    'This macro splits data into multiple worksheets based on the variables on a column found in Excel.
    'An InputBox asks you which columns you'd like to filter by, and it just creates these worksheets.

    Application.ScreenUpdating = False
    vcol = Application.InputBox(prompt:="Which column would you like to filter by?", title:="Filter column", Default:="3", Type:=1)
    Set ws = ActiveSheet
    lr = ws.Cells(ws.Rows.Count, vcol).End(xlUp).Row
    title = "A1"
    titlerow = ws.Range(title).Cells(1).Row
    icol = ws.Columns.Count
    ws.Cells(1, icol) = "Unique"
    For i = 2 To lr
        On Error Resume Next
        If ws.Cells(i, vcol) <> "" And Application.WorksheetFunction.Match(ws.Cells(i, vcol), ws.Columns(icol), 0) = 0 Then
            ws.Cells(ws.Rows.Count, icol).End(xlUp).Offset(1) = ws.Cells(i, vcol)
        End If
    Next

    myarr = Application.WorksheetFunction.Transpose(ws.Columns(icol).SpecialCells(xlCellTypeConstants))
    ws.Columns(icol).Clear

    For i = 2 To UBound(myarr)
        ws.Range(title).AutoFilter field:=vcol, Criteria1:=myarr(i) & ""
        If Not Evaluate("=ISREF('" & myarr(i) & "'!A1)") Then
            Sheets.Add(after:=Worksheets(Worksheets.Count)).Name = myarr(i) & ""
        Else
            Sheets(myarr(i) & "").Move after:=Worksheets(Worksheets.Count)
        End If
        ws.Range("A" & titlerow & ":A" & lr).EntireRow.Copy Sheets(myarr(i) & "").Range("A1")
        With Sheets(myarr(i) & "")
    .Columns.AutoFit
    .ListObjects.Add SourceType:=xlSrcRange, Source:=.UsedRange, xlListObjectHasHeaders:=xlYes, tablestyleName:="TableStyleMedium16"
    '.PasteSpecial xlPasteFormats
End With
    Next

    ws.AutoFilterMode = False
    ws.Activate
    Application.ScreenUpdating = True
    
    Call Splitbook
End Sub
