Automatically attach backup to Cashflow

Wondering if it’s possible in the future to add the backup to the cash flow report automatically. See attached Cash Report we send to one of our clients who want to see all the backup. Would be awesome if there was an option we could check that automatically attaches the backup invoices as one PDF file. If you don’t think that’s possible, you should consider allowing us to publish this report and give our clients access to view reports where they can click the backup. Another option would be an HTML file.
