AR transaction numbering for Complete and Incomplete Transactions

Summary:

Hello Team - I have all AR transactions (invoices, credit memo) setup for approval. The transactions in complete status are getting created with 3001, 3002 etc and once approved, it moves to the numbering setup under "Manage transaction source". How can i override this setup? Because it could be difficult to the client to track invoices and CM with different numbering formats and sequence. Please see example
