Is there a common pattern for Scriptable Cart scripts to retrieve data that the Customer Center role doesn't normally have access to? We're trying to calculate tax for an order, but need access to search data from objects like Locations, Subsidiaries, the customer, Items, etc. Things that are not accessible from the order directly.

Normally i rather do all the processing from SCA and just send the very specific details to Scriptable Cart with the minimum info needed (as Tran Body mostly)
