Payment for Multiple Invoices

Payment for Multiple Invoices

When I have a client with multiple open invoices it would be great to combine those invoices into one bill or email to allow them to pay all of the invoices at once instead of multiple payments. I do a lot of work for the same clients over and over and when they have more than one invoice open I want to be able to send them a payment link with the account summary of open invoices letting them make one payment for everything open. How can this be done? I saw a post about this from 3 years ago saying that it was coming but I cant find it.
