Hi countryrumours
Welcome to the Community Forum. The cheque No. field is used to differentiate the transactions by assigning them a number.
If you change the number on each invoice to the same number (or word), it might be harder to differentiate the invoices, but at this time, the software will allow you to enter the same reference number.
As this field is designed to have unique numbers, it won't be possible to have it autofill with a word or phrase, you will need to enter that each time.
