I love when people voluntarily come on this forum, and voluntarily click on threads and then tell you to search and ask why you post a new thread........
Anyways, I doubt you are going to be "forced" into the CRJ. The CRJ usually goes pretty fast in class and there aren't many slots anyways. MIA EMJ has dominated the previous 2 or 3 classes, and I'm sure will come back around.
In a nutshell, bid the base you want. If they don't have the base, bid an airframe that is in that base. Period. You can put in your transfer first day of class, but it might take a month or 3 before it takes place.
