When a customer creates an account through smith cart I am not seeing it stored in the 'manage customers' in smith cart. I am only seeing them in DNN (regardless of if they place an order or not)

I had setup a user jsmith and placed a test order, only then was he added to the customer listing in smith cart. If they just create an account, they are only added to DNN user's.

Is there a way to either have them created in smith cart regardless of whether or not they place an order, like how DNN does it?

Additionally, how can I change/setup so that when a customer creates an account, they are autoassigned a specific role (tax exempt). It'd be nice to see that option as a checkbox if they are tax exempt then they are assigned that role, and if they do not check that box they are just assigned the customer role (and are taxed according to whether or not the state is in the 'taxable states' list. Even if I can just change what role they are assigned for now that would be super beneficial.

Thanks!
