Payment Note

I would love if you could add notes directly to a payment. For example, if I cancel a payment request - I would like the ability to add a note for why that payment is being cancelled (client paid straight into my account, BPAY payment, cancelled session, etc.) This would help me keep track of the data for paid, unpaid, and cancelled data. I know there is a space for ‘notes’ on each individual customer - but when I am looking at the history of all payment requests - this is where I would be looking for this information - notes under customer would be more relevant to information about them. Hope this make sense :)
