Hello, and thanks for your feedback! This functionality exists today in our Insight Billing product. Please navigate to Print -> Chart Notes -> Chart Notes with Attachments. This will allow just attachments and chart notes to be run.
If you have any further questions feel free to leave a comment here or contact Insight Support via Support Hub and log a case at supporthub.webpt.com or call (503) 525-0275 (option 2) and notify them of any issues.
