Income Allocation Report-- how to arrange by date of payment

I am trying to run a Income Allocation - Details report for a month period. When I run it, it organizes it in order of the client’s name. I prefer payment date, so I can more easily track with the bank. When I click the “Payment Date” heading it gives me nothing, it is read only. There has to be a way to do this, google didn’t give me anything, thanks. I have Prosper.
