Splitting multiple pdfs (AR Invs/CMs) to combine into 1 email

Hello! So I understand Acumatica can send out AR Invs/CMs in mass, by email, which sends 1 email per every 1 document. I also know if we multi-select and then go to Print, we can send out multiple documents combined into 1 pdf, with 1 email. These options are great, however there are certain clients who would instead prefer to see multiple documents split up into 1 email. Do anyone know if there is a way to do this?
