How to link multiple brands/websites to territory

Hi Guys,

We have around 100 brand/product specific websites which we want to assign to 10 territories (10 each) and track the matrix for each  territory in terms of total visitors, total leads, total chats, total sales etc. done in each brand/website and aggregated together in territory to see the consolidated view. We can only see only to have brands in SalesIQ and no way to group them together and assign to a territory. Also we want to assign the visitors/leads coming from websites only to the operator(s) which belongs to that territory not to any other user, there is an option to create department and assign users based on rules but we are not sure is there any way to assign department to territory or brand/website to territory. Is there any way by which we can achieve this?
