Yes absolutely.  There are two ways to do this :  

1) Either ensure your shop plug in can assign a different shipment service for the first order, and then follow on orders.  Then ask huboo to map these to the appropriate service.

2) Ask us to switch on our 'VIP Override'. This will automatically send the first order to any client as first class 24 hours service for a great first impression then any repeat orders as second class 48 hour service.  Please note if you are a new client then it will take a subscription period to build up our shipment history to know whether your customer has ordered before.
