How to notify all vendors about an order?

[alikon1]

Virtuemart 3.2.14
Created some vendors and products for every vendor.
For example:
Vendor 1 - Product 1
Vendor 1 - Product 2
Vendor 1 - Product 3
Vendor 2 - Product 4
Vendor 2 - Product 5
Vendor 3 - Product 6
Vendor 3 - Product 7
Vendor 3 - Product 8
Vendor 3 - Product 9

Then, when shopper buy Product 2, Product 4 and Product 8 in one order, how to notify all vendors about their part of order? Vendor 1 about Product 2, Vendor 2 about Product 4 and Vendor 3 about Product 8.
Because now only main admin recieves order mail where is no mention of vendors.

As I understand from this topic, virtuemart hasn't multi vendor functional and it'a impossible.
