Is it possible to send PDF invoice via email with Amember 4?

I would like to make more easier to access to PDF invoices for admin, what of the following would be possible to apply?

1) Send and email to admin with the PDF invoice attached when a payment is completed.
2) have the direct download link to the PDF invoice in the dashbord nearby the new users
3) have the direct download link to the PDF invoice under payments menu -> invoices

With direct download link I mean I can just download, not go to the user page payments and then download.

Thanks a lot,
Nicola.

no ideas ????

If someone as suggestions those would be very much appreciated, thanks in advance...

This is a built-in option in V4. Under SETUP CONFIGURATION click on PDF Invoice and tick the checkbox where it says to email a pdf copy of the invoice.
