The Problem:

Drop Shipper emails contain items from both drop shippers and we can't seem to get them separated. We have two drop shippers that we would like to send separate emails that contain only the products they manufacture. We are currently only able to get one email out of the system and it contains both drop shipper product items which will be very confusing to the drop shipper if we send it along and tell them to "just look through this consolidated order and pick the items that you make, make them, and send them to the address above".

What we have tried: (doesn't work)

We have set up the drop-shippers as MANUFACTURES with their own email addresses but only ONE email is fired off AND it contains BOTH drop shippers products.
We have set up the drop-shippers as VENDORS with their own email address but only ONE email is fired off AND it contains BOTH drop shippers products.
We have added 2 additional steps to the "Process New Orders" workflow with specific email addresses and they still haven't received a New Order email.
We have set up 2 separate email templates for each drop-shipper and assigned the templates using the appropriate Drop Ship E-mail Template.
We have confirmed that the correct vendor is assigned in the properties section under Edit Product during that test.
We have confirmed that the correct manufacture is assigned in the properties section under Edit Product during that test.
We have confirmed that the correct ship mode is assigned "drop ship from vendor" during each test.

BV is so functionally rich I have no doubt that it can perform such a easy task ... the question is how to configure it to do such a thing.
