Extra ref being on report print outs

SUGGESTED

Hi I’m just trying to set up a new report to be printed. It’s the sales day book but I would like to see ref and extra ref on the printouts. How can I adjust reports to do this.  We have sage 50 accounts cloud. I’m looking to do this to see which of our customer invoices  can be  matched to payments,  having print out showing for our paper files.
