I make invoices as part of my business on a monthly basis, all kept inside one Numbers spreadsheet on iOS Numbers for iPad. I have one invoice per tab. Each month I want to be able to email just one tab's tables to my clients (the invoice for that month), but currently the only email options for pdf send the entire Numbers spreadsheet. There isn't a way to select which page/tab I want to email. This would seem to be a major shortcoming unless I am missing something? I am running Numbers version 1.6 (510) and iOS 5.1.1 (9B206) on an iPad 3 (new iPad) Wifi device.
