Sending emails in the invoices module


As you can see the in the images, in the clients module i can select various, and then click send email, but in the module invoices, i can’t do that, is that because of the type of module or i need to do something?

Thanks :slight_smile:

PD: The images are in spanish language. -> Correo= Email.

To do that do i need to add some code to the listview.php? Or what, some help pls!
