set 2 accounts contact
Option to set multiple contacts on a supplier profile for difference purposes.
For example, 1 contact to send/submit the sales invoice and a different contact(s) to receive the automated reminders.
depending on the supplier's payment process, the email address to submit the invoice might be an automated inbox (unmanned) or a different department from the account payable team which needs to approve the invoice first.
