Clone Invoice - removal of previous tax point

Clone Invoice - removal of previous tax point

Hello, when cloning an invoice the previous invoice date remains in the field.  if you forget to take this out it affects the previous month end figures.  I cant think of a reason or purpose why it would be left in? it serves no use and is very frustrating as you then have to go back and amend the date in sage and zahara.  Whilst we are talking about dates, the helpful fields of searching every 30 days and every 60 dates are handy BUT many suppliers invoice quarterly therefore a 90 days search option would be very useful.
