Is WP E-Comm. Plugin capable of multiple accounts?

So I am building an E-Commerce site with the WP E-Commerce Plug in. So far I love how easy it is to set up. Then my client called and had a request for the shopping cart, and I don’t know if I can accommodate it with WP.
My client would like the ability to have his affiliate salesmen have individual accounts on the back end of the shopping cart. He would like them to have the ability to enter their individual sales, and to be able to keep track of their stats for comission etc. Is there a way that I can accomplish this with the WP plug in or do I need to use something else?
