Add options to saving invoices

A lot of invoices I create I manually print out immediately after I create it. When I create an invoice, the only option I have is to create a draft, or send a pdf in an email. I have to go to the email option, go back to the invoice list, find the invoice, and then generate a pdf. It's a minor annoyance, but it would be nice if I could just immediately generate a pdf when I create the invoice, rather than being forced to email.

Thanks!
