Ahhh, but you wanted the easiest setup.
Let's see - created two x-port stations, with remote coverage paths to the two LD numbers that you want. Give the two x-port stations a unique COR that you are not using elsewhere.
Now create a new station for the lobby, or where ever you want this phone to be placed. Create a new, unique COR for it, also - Outward Restricted, and with calling permissions (page 3) only to the unique COR that you just set up for the two x-port stations.
Last step; give the lobby phone two speed-dial buttons to the two x-port stations, and label each as your two LD destinations. Customer selects SD 1; call routes to remote coverage path 1; which is your LD number 1. Same setup for the second number: SD 2 = r2 = LD 2.
