where do shipping estimates originate from for FedEx accounts and Unit Shipping?

Hi, are shipping estimates defined by the "from" address in a fedex account and unit shipping, or can that manually be entered? Thanks, Charles

In the admin setup for FedEx

Code:

---

First line of street address
Enter the first line of your ship-from street address, required

---

Is it possible to have 2 ship-from addresses? Product is shipping from two different locations.

How would the code know from which location??

What estimator would be used if a customer purchases 2 items that ship from different locations??
