View Paypal %OnlinePaymentURL% link after generating Invoice

Hello,

Most of my billing is done in person. I would like to know if after I generate an invoice I could go directly to the paypal link for payment. Ideally I could create the invoice on my Android and process the payment on the same device immediately after generating the invoice. I would just need to be able to access the %OnlinePaymentURL% link somehow without going to the customers email to view it.

Thanks,

Tony
