b2b solution for wp-ecommerce

Is there some plugin for wp-ecommerce which could help me with the following
1.Enhanced spending control – Set up authorized user and parent/child billing options if companies have multiple departments/locations

2.Multiple Levels of Order Approval — If company have multiple people placing orders online. They want to be able to monitor all orders that are placed. We should have multiple approval levels for online ordering so they can keep track of everything that their company orders.
