Reprint FreeText Invoice generate via Sales Ledger

It would be a great idea if the facility to reprint, view invoices that have been generated via Sales Ledger, enter transaction, free text invoice can be be made available. At the moment the options are shown on the transaction enquiry however when selected it states no data available which is a nuisance if you wish to correct or amend then reprint. If a correction is required you then have to reverse the invoice and reinput it again which is very annoying. So please can we have this updated.
