Rate Browser

I have used ShipStation for over 7 years and the Rate Browser function is something I use many times a day.
With the new Legacy version, I am no longer able to use the Dropdown that lists all of the saved "Ship From Locations", instead it asks for a zip code. This is incredibly inconvenient now as the information needed is saved within Shipstation already and requires additional steps for me on the back end before moving to the next step in the Rate Browser. Creating a label is now inefficient and I beg for this function to be added back! Please!!!
