Question / Problem:
Is it possible to have PDF's with one multi page invoice in the same email as PDF's with multiple invoices?
Answer / Solution:
This is unfortunately not possible. You can only have one setting per email.
The two settings are "Multiple document per attachment" or "One document per attachment".
If you select "Multiple document per attachment" Online will separate on blank pages. If blank pages are not present, Online will separate all pages in the attachment as individual invoices.
If you select "One document per attachment" Online will handle the attachment (PDF, TIFF, PNG or JPEG) as one invoice.
You can not mix these two settings for one email.

The same applies for Online Connect. You can only have one setting there too.
