Bringing family over later on

Hi, I plan to come over to SA as a Bachelor, and then bring my family over quite a bit later (probably more than one year later). My GC allows for family status. Right now, I understand most bachleors are being placed in ABQ, and so that is where I will probably wind up. On the other hand, those bringing their families are generally getting placed in Rakah. So, I am wondering if/when I decide to bring my family over ... will we be forced to live in ABQ or will I get put on another list that will allow us to live in Rakah? I am hoping to find examples of people who have been allowed to switch once the change to family status happens.

Does anybody know of others who have been allowed to switch compounds?
