"mailto:" with automatic pdf attachment

Hi there,

I write my invoices in Numbers and am adding email addresses of my creditor.

Would it be possible to create a hyperlink that by clicking on it automatically creates a pdf of the document, opens the Mail App and prewiretes the email AND adds a pdf of the Numbers document?

Something like <mailto:John.doe(at)iCloud.com&subject=Invoice&body=Here your invoice>

but with pdf attachment of the numbers document

Thanks for your help

Jan
