How does housing work if I would like to room with someone specific?

How do I go about applying for housing if my friend and I would like to room together?

Looking at the reslife page for selecting roommates, it appears A&M has changed the procedure from previous years and it seems like not only can roommates select one another but you can select your room, depending on the dorm. In years past, you chose roommate over dorm or dorm over roommate, depending when your housing contracts were signed.
Here is the page I found that outlines the process.
