Importing Invoices

Importing Invoices

Hi,
I am importing invoices from a CSV file and have a couple of questions:
  1. Am I able to determine the email template the invoice should use as I have two based upon how they pay?
  2. When importing can the invoices be automatically emailed once imported?
  3. If not, there is a problem when trying to send more than one invoice as the system say "...experiencing a roadblock" and invoices were not emailed...." - this happens everytime..
Regards
Chris
