1-click individual package purchase

Hello! I would love the option to send a specific package to a customer to purchase instead of the entire list of packages and hoping that could be a future feature. For instance, I have someone who'd like to purchase a Consultation and another who'd like to purchase a Medium Package. It would be fantastic if I could send that to them directly for a 1-click purchase and eliminate confusion in lieu of creating an invoice since I don't begin the work until the package has been purchased after a design request has been submitted. Thanks for your help!
