Multiple payment Options on payment request

Hi,

When generating payment request. How can you include multiple payment methods on the request.
i.e. PayPal, Bank Transfer, Braintree. So customer have multiple options to pay?

Also I’m finding that when emailing payment request the pdf in the email is sales order not payment request. The email body doesn’t have click here to pay link and payment request pdf itself from url next has long URL not link.
