[The Hub] Mark invoices as paid without sending

For some payments, I prefer to manually send the invoice and request a specific payment method (not Stripe). However, you cannot mark invoices as ‘paid’ unless they have been sent to the client via The Hub. It would be really helpful to be able to mark the invoice as paid (and send a receipt) without having to send the invoice to the client via The Hub. At the moment I have to resend the invoice and that is confusing to the client.
