Usually, my organisation sends grant agreements and similar legal documents to the primary contact of the grantee organisation, as opposed to the request primary contact. However, the email options from within the request are only the (request) primary contact or the applicant account and the 'generate letter' option has only the request primary contact.
I'd like to see the organisation primary contact as an option at least for emails, so that we can send emails and attachments merged from the request to them.
