Order status management

Hi,

We have recently purchased Hikashop Business, Hika Market Multivendor.

Our products are manufactured and allotted to multiple vendors to sell those on our portal.

After customer creates the order, email notification goes to the vendor and the main vendor(manufacturer).

Now, the requirement is, we have created order status as- Installation. Our products need to be installed by the manufacturer. So, once the order status changed to installation, one email notification should go to a separate installation team serving in the vendor/delivery location only and the installation team will have a separate login and a page where only orders of installation status of there allowed delivery area must be shown.

E.g. A vendor in London sells a product in London and the installation team of manufacture based in London only should receive email notification of status installation only so that the team can go to the customer's place and do the necessary installation, come back and change the order status to completed.

How to manage the above scenario?

Thanks!
