Reapplying Conditional Formatting To Current Sheet

I have written a code that copies the formatting across a row (in first sheet). It then goes to the next sheet deleted all conditional formatting and pastes to the end row. This works well for applying to new sheets.

But how do I reapply to the current sheet. Is there a way to get each conditional format and give it a new range so it includes any recently added rows. I have found I need to delete all formats on the sheet first as it would otherwise duplicate the same format over and over each time.

Code:
For nn = 2 To 9 'Each ws In ThisWorkbook.Worksheets
Set ws = Worksheets(nn)

Length = FindLast(ws)
'%%%%%%%%%%%%% Copy Format %%%%%%%%%%%%%%%
ws.Activate
FullLength = FindLast(ws)
ws.Range("A3:AN10000").FormatConditions.Delete
