Profit/loss report showing unpaid invoices


Hi everyone, recently new user to Sage accounting.

I have just had a nose at the profit/loss report which I plan to use at year end for when doing my self-assessment, but have noticed that in the Sales section it is including unpaid invoices within my Total sales, as i'm using 'cash basis' when doing my tax returns i'd like to exclude these from my report - is this possible?

No biggie if not, because I can work it out manually, but I guess the point of having fancy accounting software is so that I don't have to?
