Has there been any progress on this? For our business, it would be extremely valuable to have different numbering sequences for Invoices and Credit Memos. Our CM's do not follow the same sequence as our Invoices so we manually have to change the sequence every time we wish to enter a Credit Memo. This often causes future invoices to be created in the wrong sequence not matching our standard convention which is very frustrating and confusing for both customers and our A/R Team.
