Define a user that can only manage orders and inventory in Marketpress

Hello WPMU,

Is there a way to define a "shipper/logistics" user that has only access to the "Manage Orders" and "Products" pages in Marketpress. I need to outsource my logistics and would like my logistics firm to have access to manage the orders and update inventory without being able to access everything else.

Or do you have a better suggestion for achieving the same effect?

Thank you
