Store Manager in Marketpress

I'm the webmaster of a website and not the shipping department. I need to be able to grant access to the shipper to login and add the tracking code and see the order but they should not be able to edit the entire website or be listed as an 'Editor'.

Anything below the 'Editor' role in Wordpress does not allow to see the orders or manage them.

Basically the shipper needs to be able to login, see the order, (not edit it) and see the shipping method that has been chosen on the order by the customer, then ship and enter the tracking number.

Any ideas?
